co.mments.com allows you to create bookmarks of specific blog conversations that you want to track. This tool can be used to monitor blogs where you have posted a comment and want to see if anyone has responded, or perhaps you just want to monitor a particular blog entry to see if others have added comments (started a blog conversation).
Personally, I think this is an interesting idea. On several occasions I've posted comments blogs, only to forget to check back for a response. It was only days later that I remembered the posting and had to try hard to remember the specific blog.
This tool allows you the option of having blog comments e-mailed directly to you. This is a great alternative if you don’t want to subscribe to the blogs RSS feed. As another option, you can share to co.mnents links with friends or the public at large.
Because I think this idea has merit, I'll be giving it a try. It appears very easy to use and you can even arrange to be e-mailed when comments are added. Only time will tell if co.ments.com catches on like del.icio.us.
