My thanks to all who have contributed comments since March 2004, when I first migrated to Typepad and enabled comments. However, managing comments has become more of a challenge the last couple of months, so I'm moving to trackbacks rather than comments for most posts. You still have three good options for commenting on posts: (1) Comment as a post on your own weblog, with or without a trackback to my post; (2) Email me your comment and get a personal reply; or (3) Just grasp your monitor with both hands and shout at the screen. No, I won't hear you, but you'll feel much better when you're done. It works great for driving anyway.
