Hmmm... thanks for the suggestion. What else is out there? I've looked at a Disqus plugin—will that work with CB? Commenting is going to be potentially very important on the site, and I need to have something that isn't as anonymous as an anonymous log-in, so tied to Twitter/FB/etc., is important.
I also need to have the commenting NOT show up in a tab, but rather in blog-style, directly under the profile. Who was experience with this?
