Here are some highlights in chronological order and what you can learn from the process:

1/ August 5 2020: Janel digs into '50+ newsletters' (note the number to build credibility) and creates a thread to discuss the lessons learnt. She also mentions that this is for a side project, which raises awareness of something she may be working


2/ August 5 2020 (cont): Each tweet in the thread is focused on a key message, with clear pointers for newsletter writers to


3/ September 1 2020: Janel tweeted about #buildinginpublic (note the hashtag) with @pabloheredia24 for @makerpad's challenge. While the project is https://t.co/tMb1qCnxVY and not NewsletterOS, Janel is getting in the reps on how to build in

The entire discussion around Facebook’s disclosures of what happened in 2016 is very frustrating. No exec stopped any investigations, but there were a lot of heated discussions about what to publish and when.


In the spring and summer of 2016, as reported by the Times, activity we traced to GRU was reported to the FBI. This was the standard model of interaction companies used for nation-state attacks against likely US targeted.

In the end, the difficult question of attribution was settled by us pointing to the DNI report instead of saying Russia or GRU directly. In my pre-briefs with members of Congress, I made it clear that we believed this action was GRU.
