AFTER CHANGES WE ARE MORE OR LESS THE SAME: I'm in the process of installing Disqus as our new comments system. Why Disqus, and not Blogger? Because I like "likes," and I think it's a better platform. If I'm wrong, I will be the Anti-Tom Petty of backing down.
All existing comments are being imported into the system, but it make take 24 hours.
Please let me know how this is working out for you, in the Comments, or if necessary shoot me an email.
update! To edit the name which is displayed with your comments, go to your Disqus account settings to Profile, and change your Full Name to the one under which you'd like to post.
second update: To see older comments during the transition, check our mobile site.
