Tom Mangan shuts it down.

Blogging was fun till it started getting to be too much like work: scanning dozens of blogs and news sites every day for blogworthy posts, then thinking up something to say, then saying it, then correcting all my typos. Time spent blogging was not spent with books, music, movies, family, physical fitness (I gained 15 pounds because I had to give up my workouts to free up time to blog). Lately I had come to dread it. Dread's always a good sign it's time to move on.
