While working late last night to sign up for some social networks that I still hadn't joined, 111 now total, and remembered Disqus. I guess at some point they moved their model to more of a comment moderation, interaction social network and community. Interesting idea, to create community around comments on multiple blogs.
I'm trying to set up the comments section for this blog as a test drive. If you stop by today, please comment, and sign up for disqus if you want to check out the system.
