Given the increasing number of forum users, and the difficulty for newcomers without a social network of getting input on their posts, I thought I'd highlight this Facebook group (I have no affiliation to it, if that matters for a FB group).
It doesn't look very active, but I think if you post an open-access Google doc in there, many people will still receive a notification about it and potentially read your work.
The FTX collapse took place in November 2022. Among other things, this resulted in a lot of negative media attention on EA.
It's also worth noting that this immediately followed a large (very positive, on the whole) media campaign around Will MacAskill's book What We Owe the Future in summer 2022, which I imagine caused much of the growth earlier that year.
