Track your conversations with coComment

coComment: "... enable you to efficiently track your comments comments and conversations with others across the blogosphere." I am just giving it a go at the moment and it has been very useful so far. Have you ever wondered where have you left a comment, and whether anyone else has replied you? Sometimes it can be frustrating to scan through past articles that you might have commented. I used to use something like del.icio.us to help me to remember, but coComment actually notify me when more people commented on the same blog post.
