At Lotusphere 2007 last week, I heard Sean Burgess mention this web service for tracking you comments online. Sounds good to me. I signed up today. You have to add a plug-in for Firefox. I ran a quick test and I didn't see my comment listed yet. Oh well, I'll keep playing. It's got to be better than using my memory to track all the comments I make on blogs. That's not cutting it anymore. Check out CoComment.com
