I just read on Scobleizer that coComment is launching a service that tracks the comments that you make in the blogosphere. Using coComment, you can:

1) See a centralized view of all the conversations (conversation = blog post + comment thread) that you have commented in. It’s not clear if they handle the recursive nature of this. For example, Scoble posts, gets 10 comments, I trackback and add my 2 cents, I get 5 comments, …. This is all one conversation but spanning many blogs.

2) Put a little widget on your blog that shows your readers what comments you’ve been making on other blogs. This is really what gets me most excited. Every comment you make on another blog is a little piece of your identity that now belongs to someone else. By making these comments visible on your blog as well, your comments become tied to your identity. That’s why, often times, if i have something insightful to say on a topic, I would rather post about it on my own blog rather than comment on someone else’s post.

3) Get alerts when conversations you’re involved in get updated.

My take: Great idea. Questionable implementation. However, to be totally fair, I will reserve judgement until I get a chance to really sink my teeth into it.

I have discussed a similar idea with several friends over the past couple months and just about everyone has agreed that there is a need for this. The concept of centralizing the decentralized nature of the blogosphere has already manifested itself and this is yet another example. Sort of making a personalized Usenet reader out of the blogosphere.

However, the implementation that I have sketched out is simpler and would not involve third-party bookmarklets. I’m not going to go into details right now but if I do get time to hack it together you’ll see what I have visioned. If anyone is curious, shoot me an e-mail.
