A related request: there are a lot of goals common enough that better achieving these goals should be of interest to a large-ish portion of LW. I'm thinking here of: happiness; income; health; avoiding auto accidents; reading more effectively; building better relationships with friends, family, dating partners, or co-workers; operationalizing one's goals to better track progress; more easily shedding old habits and gaining new ones.

I think this would be very helpful (esp. income, as for most people it would seem to be the whole of success at utilitarianism).
