Took the survey; Did everything but the IQ test. I recognized some of the questions, and I decided I didn't have an extra 40 minutes to spare.
I just donated Round(1000 Pi / 3) USD. I also had Google doing an employer match.
Strangely enough, I went through the 'donate publicly' link, but chose not to use facebook, and in the end it called me 'Anonymous Donor'.
I just donated $250. Can't afford as much as last year; I switched to a lower-paying job that makes me happier.
