Talk about it. Thats what coComment allows you to do, talk and view what you have spoken about and where. I stumbled across this interesting site on Paul Stamatiou's blog. Straight out of the horses mouth, here is how coComment explains itself:

coComment is a service which will help you track, organize, and share all your comment-based conversations on the web.

I am currently signing up to make use of coComment and will provide updates as I get in to using it. Apparently the way it works is that everytime you post a comment on any site (Blog, Flickr, News site etc) coComment will make a copy of the comment and save it in your personal folder at coComment. You can then visit this folder and trackback your own progression through conversations. You can also be alerted to any new comments on the same thread.I think this is a fantastic tool since I spend alot of time checking back on sites that I have made comments as well as checking my mail for alerts on threads.More to come soon.
