As you’ve probably noticed, I’m going to give Disqus another try. We’ll see how it goes; if it turns out to be more annoying than CoComment, we’ll simply go back to that.
UPDATE: No way. Disqus is far more annoying than CoComment can manage at its most quixotic. All the new comment systems require a move to the newer Blogger interface to work properly, which significantly reduces one’s ability to control the layout of the blog.
UPDATE 2: Part of that may have been my fault. I may give it another whirl later. But it’s not promising that the Disqus Appearance Settings page gives you two options: Preview and Cancel… the SAVE option is conspicuously lacking.
