I don’t agree much with Andrew Sullivan on politics these days (but, with Andrew’s record of instability, that may simply mean I only need to wait awhile until he becomes conservative again), yet I largely agree with him on blogging.
Of course, Andrew Sullivan blogs on a considerably more prolific and professional scale than I do. He is infuriatingly intellectually dishonest, shamelessly manipulative and propagandistic in his arguments, but he otherwise does a pretty commendable job. (The backing of a major magazine and a budget providing funding for a staff undoubtedly helps.)
