It's worth pointing out that the $100 you "donate" probably goes much, much less far than a $100 donation to an effective charity. So it might be better to think in terms of shifting $100 in federal funds. That makes it seem like a lot less of a slam dunk to me. Would I take half an hour out of my day to move $100 from an ineffective government agency to an effective one? Meh. Feels like my other attempts at altruism probably have a much higher expected impact.

I'm also worried about getting called up for jury duty if I re-register to vote now that I'm living in a different county.

On the whole though, fairly persuasive.
