First off: as one of Ethan's current Astra Fellows (and having worked with him since ~last October) I especially think his collaborators in MATS and Astra historically underweight how valuable overcommunicating with Ethan is, and routinely underbook meetings to ask for his support.
Second, I think this post is so dense with useful advice, so I made anki flashcards of Ethan's post using GPT-4 (generated via ankibrain [https://ankiweb.net/shared/info/1915225457] , small manual edits.)

I think btw it gets more value than scholar support because it's a proactive service we offer to all scholars on a given stream, rather than waiting for them to only come to us when there's a problem.
I spend a fair amount of time on my projects helping people prep for meetings with their supervisors, yeah. I also used to have scholars edit my written reports before sending to Ethan.
