Ditto, although I cut back my participation mostly because SO turned into a frustrating experience.
It's not rewarding to type out a good answer only to be beaten by a bunch of half-assed answers that appeared first. Nor is it rewarding to type out a detailed answer only to have someone come along 5 minutes later post basically the same thing (including stealing the code example) and get chosen as the selected answer. Add to that the deletionist moderation ("Oh, this post from 2008 should have been on SuperUser instead so we'll just delete it") and a number of other issues. At this point, I generally find participation in SO significantly more frustrating than rewarding.
I still get about +30 rep per day, but almost all of that is from two answers that date to the very early days of SO.
