Web service coComment helps you track your blog comments and conversations, aggregating your conversations from across the blogosphere to one handy location.

Whether you’ve commented on a blog or you’re just following a blog-based conversation of interest to you, coComment can let you know what’s been added to a particular discussion in real time.

As many of you may know, keeping up with comments on Lifehacker can be a real pain, as we currently have one measly RSS feed for all of our comments. coComment looks like it could be an excellent way to keep up with those posts where the conversation started in the comments is just as important as the post itself. Unfortunately (for Lifehacker readers, at least), coComment currently only supports Blogger, MSN Spaces, MySpaces, TypePad, WordPress, and Xanga. Not crappy MovableType.

coComment is currently in beta and requires an invitation code to register, but having signed up for an email notification this morning, I promptly received an invite. If you’re interested in coComment, give it a try.
