I precommit to upvoting and saying positive things about anyone who comments saying they've donated. Hopefully tha will move at least some people to the positive side of the akrasia/altruism balance.
I also set up a recurring unrestricted donation to GiveWell for the first time, for what turns out to be ~13% of my net income. This is posted in agreement with FiftyTwo's rationale, not as a signal.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
