Twitter is an invaluable resource for product people, much better than LinkedIn content.

Use it, and tell your PM friends to use it too.

But whom to follow?

Check out this list:

I’m a fan of product/UI/strategy teardowns as a way to "learn-by-doing".

One teardowns resource I’ve recommended for a while is https://t.co/BSeVzFZSNG

There are a few out there (fellow PMs, please share more teardown resources below).
12/

Lastly:

Be sure you want to be a PM. It’s a great role. I love it.

But PM isn’t the “step up” that ppl think it is.

There are other paths to success.

So choose it for the right reasons & be open to cutting your losses if you find out it isn’t for you

All the best!

If you’re a Startup trying to compete with a Megacorp—the 800-pound Gorilla in the space—you need to understand the tax inherent to being a Gorilla

And then you need to make that tax work against the Gorilla—with your product's positioning & features

A thread on Gorilla taxes👇🏾


1/
Collaboration Tax

Getting two or more product groups at a megacorp to collaborate on creating a seamless end user experience is the hardest problem in computer science.

(I am not joking)

Examples of Collaboration Tax:

Calendly exists because the Gmail team & Calendar team haven’t worked together on creating a more seamless experience for that use case.

Loom might succeed because the Gmail, Video, Meet teams at Google are probably too busy with their own goals.

The takeaway for startups:

If you can create meaningful value by seamlessly integrating features of two or more distinct Gorilla products, you will typically have a lot of runway before the Gorilla can get its act together and eliminate its Collaboration Tax.

2/
Denominator Tax

Once a Gorilla’s product reaches massive scale (i.e. the denominator for its metrics gets very large), the pressure of OKRs & incentives will often force the Gorilla’s product teams to prioritize breadth of usage more than depth of usage.

Listening, *really* listening, is a rare superpower.

I was a bad listener most of my life.

Then I fixed that a few years ago.

Night & day difference in my leadership ability.

I learned that we can learn to listen well.

A thread on listening (and learning it from movies🎞️)
👇🏾

First, why is listening hard?

It’s because we have:
- the fear of being wrong
- an inability to be present
- a desire for validation
- a lack of curiosity
- the urge to impress
- a feeling of superiority

For an example of *bad* listening, let’s learn from this epic scene from the movie, The Darkest Hour.

The setup: World War II. There are disagreements among British leadership about whether they should pursue peace talks with Germany or an all out war.

Go on, watch the scene.


Really, watch the scene before proceeding to the next tweet.

So what can we learn from this scene about listening?

The superficial lesson is not to interrupt others.

But the deeper lesson is that most of us are like Churchill w.r.t. listening.

How so?

While we may not interrupt vocally, *we are interrupting others with our thoughts*

A thread of product management frameworks:

(this might be useful if you are a product manager, product leader, or founder)

Before we jump in:

Frameworks will not fix all your problems.

Used right, they should help you
1) better understand your context
2) create structure for problems
3) communicate ideas & solutions

I often use these frameworks in my product work, sometimes without realizing it.

1/
3X framework (Kent Beck)

A product can be in one of 3 stages
1. Explore
2. Expand
3. Extract

For product leaders this is the most vital framework to understand because almost every important decision should account for the stage your product is

Examples of decisions you can make more rigorously with the 3X framework:
- optimize for inputs, outputs, or outcomes?
- set more qualitative or quantitative goals?
- how to measure progress?
- what skills to look for?
- how to evaluate PMs'

2/
5Qs for product rigor

1) Who is the customer?
2) What is the problem/opportunity?
3) What is the main customer benefit?
4) How do you know customers want this?
5) What is the customer experience?

This framework provides useful structure for product proposals, reviews, etc.

A surprisingly high % of stupid arguments & fights on Twitter are rooted in a tiny number of fairly obvious fallacies.

Stupid arguments & the fallacies that feed them, a thread:

Fallacy 1/

Just because it’s true that all squares are rectangles, you argued that all rectangles must be squares. (And you did it with so much swagger.)

Example of Fallacy 1

X says: Successful people aren’t afraid of hard work.

Y argues: That’s BS. I work 90 hours a week at Tech Co and am still stuck in this dead-end job.

Fallacy 2/

Just because you found an exception to a general pattern, you argued that the entire pattern is false.

Example of Fallacy 2

X says: Venture capital is useful for startups.

Y argues: Not true. Foo’s startup took VC money and they crashed & burned.

Z piles on: I agree with Y. In fact, Bar’s startup did not take VC money and it’s worth a bajillion.

Why does Your Manager’s Manager (YMM) request a deck/doc during a meeting, says it’s urgent, and then doesn’t respond for days after you create & send it?

Or, why does YMM often respond with trivial feedback (e.g. formatting) & not substantive feedback?

Answers in this thread👇🏾

Have you set an entirely new password on a site & said to yourself: “surely, I’ll remember it becos this site is so important for me”. Have you then gone on to forget that password the very next week?

Me too.

The reason for YMM’s odd behavior & my password optimism is the same.

That reason is the Focusing Illusion, first described by Daniel Kahneman.

The Focusing Illusion:
Nothing in life is as important as you think it is while you are thinking about it.

When YMM asked you to create that doc as one of the follow up actions during the Product Review, YMM fell prey to the Focusing Illusion.

Trust me, YMM had no intention of making you do busywork.

YMM truly believed that it was very impt & urgent to create that doc & review it.

This was YMM’s conception of how much of their future time was appropriate to spend on the item for which they requested that doc (Item A):

@curaffairs The author doesn't know enough about search to have written that article and the reason he's having those problems is AI algos like Rank Brain and Google's attempts to use natural language processing nothing to do with SEOs.

1/x

YMYL is not evaluated at the site level, but the query level.

Again this is on Google, not SEOs because they want to surface better sites.

And those devaluations are part of Core Updates which SEOs like me recover sites from.

2/

Featured Snippets are not optimized for - you can use certain HTML to be pulled in one but there is no definite use case where Featured Snippets are shown or that your site's will show for it. Also doesn't always come from the #1 result.

& that's Google not the SEO.

3/

Also there are many times when an SEO doesn't want their site in the Featured Snippet cuz it doesn't result in a click to the website. But we have no control over what Google pulls as Feature Snippets except to put in a meta tag to exclude us from them

4/

And Neil Patel is not an SEO. Most senior level SEOs see him as nothing more than a scammer because reportedly he's ripped them off by stealing their content and articles and passing them off as his.

There are lots of problems with ad-tech:

* being spied on all the time means that the people of the 21st century are less able to be their authentic selves;

* any data that is collected and retained will eventually breach, creating untold harms;

1/


* data-collection enables for discriminatory business practices ("digital redlining");

* the huge, tangled hairball of adtech companies siphons lots (maybe even most) of the money that should go creators and media orgs; and

2/

* anti-adblock demands browsers and devices that thwart their owners' wishes, a capability that can be exploited for even more nefarious purposes;

That's all terrible, but it's also IRONIC, since it appears that, in addition to everything else, ad-tech is a fraud, a bezzle.

3/

Bezzle was John Kenneth Galbraith's term for "the magic interval when a confidence trickster knows he has the money he has appropriated but the victim does not yet understand that he has lost it." That is, a rotten log that has yet to be turned over.

Bezzles unwind slowly, then all at once. We've had some important peeks under ad-tech's rotten log, and they're increasing in both intensity and velocity. If you follow @Chronotope, you've had a front-row seat to the

Here's an overview of key adoption metrics for deep learning frameworks over 2020: downloads, developer surveys, job posts, scientific publications, Colab usage, Kaggle notebooks usage, GitHub data.

TensorFlow/Keras = #1 deep learning solution.


Note that we benchmark adoption vs Facebook's PyTorch because it is the only TF alternative that registers on the scale. Another option would have been sklearn, which has massive adoption, but it isn't really a TF alternative. In the future, I hope we can add JAX.

TensorFlow has seen 115M downloads in 2020, which nearly doubles its lifetime downloads. Note that this does *not* include downloads for all TF-adjacent packages, like tf-nightly, the old tensorflow-gpu, etc.


Also note that most of these downloads aren't from humans, but are automated downloads from CI systems (but none are from Google's systems, as Google doesn't use PyPI).

In a way, this metric reflects usage in production.

There were two worldwide developer surveys in 2020 that measured adoption of various frameworks: the one from StackOverflow, targeting all developers, and the one from Kaggle.

Chess may be a good analogy for explaining the difference between a descriptive model of reality and a generative model of reality.

A descriptive model of chess will describe the rules (i.e. initial setup, allowed moves, points per piece, objectives). This tells you how a chessboard might evolve and also narrows the combinations of realistic chess positions.

In contrast, a generative model involves the actual gameplay between competing players that follow the rules. It generates new styles and patterns. It establishes new strategies and tactics. It generates new openings, middle gameplay, and end game tactics.

A generative model is an evolutionary model that leads to emergent behavior. As a consequence, a master of chess is able to recall the layout of chess positions in a real game in an instant, yet is unable to remember pieces placed in random positions.

That is because causality is present in the movements of pieces in a chessboard. An intuitive system like the human mind is able to capture that causality as a means to understanding and recall.

Years before Andy Grove was attributed with the phrase:

"Whatever can be done, will be done"

A lot of us technologists assumed this was the case anyway.

It's a truism.

What if we could track every person on the planet in real time?

Or at least everyone in a major city

🤔🔮


So, given someone has this idea.

Then the only question is can it be done.

Well, we're already installing all the tech to do this for autonomous vehicles, drones and smart city infrastructure.

It really wouldn't be a huge leap to do that for people.

But how might that be possible 🤔

Sure we can already do it with phones right, but not everyone has a phone and sometimes the batteries die blah blah.

Could we do it in a way that it was difficult to circumvent, and always active?

Well, maybe we could if we put our thinking caps on about the problem.

--- this line intentionally left blank ---

Now I'm going to enter the wild world of wild speculative futurism, so take everything else with a pinch of salt 🧂

--- this line intentionally left blank ---

Turns out cell phone towers pinpoint the location of your phone as part of how they work.

And then as you move around you switch from one tower to another.

I think most people get this.

So, today, for the first time in 25 (!) years of Apple, I downgraded. From the 2016 MacBook Pro to my 2013, which I had kept in a drawer...


It was pretty simple to do—Apple Time Machine backups let me do it with one click.

That first tweet captures, in two pictures, how badly Apple has “lost the plot” (to quote @wylieprof). On the right is the Apple MagSafe adapter, from 2013. On the left, what I had “upgraded” to.

Thanks, Apple! I really was nostalgic for worrying about yanking my computer off the table.

Oh and I really appreciated not knowing if my computer was charging. What was great was the little whoop sound you used, so that the speaker before me could be informed I was charging my laptop.

Before I begin, it might be worth explaining the Malay conception of the spirit world. At its deepest level, Malay religious belief is animist. All living beings and even certain objects are said to have a soul. Natural phenomena are either controlled by or personified as spirits

Although these beings had to be respected, not all of them were powerful enough to be considered gods. Offerings would be made to the spirits that had greater influence on human life. Spells and incantations would invoke their


Two known examples of such elemental spirits that had god-like status are Raja Angin (king of the wind) and Mambang Tali Arus (spirit of river currents). There were undoubtedly many more which have been lost to time

Contact with ancient India brought the influence of Hinduism and Buddhism to SEA. What we now call Hinduism similarly developed in India out of native animism and the more formal Vedic tradition. This can be seen in the multitude of sacred animals and location-specific Hindu gods

So it's now October 10, 2018 and....Rod Rosenstein is STILL not fired.

He's STILL in charge of the Mueller investigation.

He's STILL refusing to hand over the McCabe memos.

He's STILL holding up the declassification of the #SpyGate documents & their release to the public.

I love a good cover story.......

The guy had a face-to-face with El Grande Trumpo himself on Air Force One just 2 days ago. Inside just about the most secure SCIF in the world.

And Trump came out of AF1 and gave ol' Rod a big thumbs up!

And so we're right back to 'that dirty rat Rosenstein!' 2 days later.

At this point it's clear some members of Congress are either in on this and helping the cover story or they haven't got a clue and are out in the cold.

Note the conflicting stories about 'Rosenstein cancelled meeting with Congress on Oct 11!"

First, rumors surfaced of a scheduled meeting on Oct. 11 between Rosenstein & members of Congress, and Rosenstein just cancelled it.
