I asked your opinion, I listened to your comments… and the vote, while not unanimous, was pretty much a landslide. Most commenters in this blog (at least, most commenters who expressed an opinion) want to use HTML in comments. And almost all the people who voted against it either don't care very much or had concerns that, while valid, have been addressed by TypePad.
So I've now enabled HTML in comments. You can use italics, bold, strong, emphasis,
and a couple others, which I don't know what they are so I'm not listing them here. Preview your comment if you're not sure. Go nuts, everybody!
Just an FYI: This means that, from now on, URLs that are posted in comments will no longer automatically get turned into live links. You can either use HTML to convert your URLs into live links, or just leave them as they are and let people copy and paste.
