The one I read most consistently is Ed Wagner's, over by Tulsa, OK, "CycleDog" (http://cycledog.blogspot.com). A good mix of stuff... teaching, social issues, transportation cycling, the "joys" of raising young 'uns...

BikeSnob NYC is pretty good, and I enjoy reading about Fatty's various misadventures with his mountain bike as well as his and Susan's heroism in the face of a really bad deal.

My puny and somewhat inconsistent efforts here: http://psyclepath.blogspot.com.
