Re See-EA and understanding the community better, have you considered the community of Sea-EAs? Or maybe go big-tent and focus on rank-C EAs? Charity Entrepreneurship's Alumni?

I think in the US it's called "Lobbying" and Open Phil has spent several hundred thousand dollars there

How about improving the climate of discussions on the forum?

(btw, I find it funny that I cringe internally more about posting 11 than about 9)

One key consideration for me is to what extent we think people who would choose to commit suicide, or people who have lived with a long treatment-resistant depression, are likely to recover and live a worthwhile life (and to what extent suicidal individuals can predict their future well-being). 

The academic literature seems very lacking here. I found a couple of recent papers:

1. https://www.sciencedirect.com/science/article/abs/pii/S0005789421000228 (a 2021 review)
2. https://digitalcommons.usf.edu/cgi/viewcontent.cgi?article=10503&context=etd (a 2022 master's thesis on the topic, studying a cohort of 8,000 US veterans within which 400 had attempted suicide). It seems pessimistic, at a glance.

They probably have a large influence on prioritization. I'd check into ALLFED

9.  EA should publicly support Israel's war effort
10. Buy a large coal mine and employ the world's poorest people
11. Only fund community builders who say they are longtermist
12. Publish the secret deal with Huel as EA's main sponsor

Engienering at LM might be better than engineering LLMs

Exactly!
