Fraser of Disruptive Thoughts, Eric of Venture Week and of Feedburner and I discussed several months ago the potential of Feedburner to ID RSS subscribers (possibly by an offering where you can elect to give your name and/or email address at the point of subscription), an idea I fully endorse, so bloggers know who our readers are. In a conceptual extension of this, MyBlogLog has developed a service that essentially allows for more robust and dynamic communities to build around weblogs. The service just rolled out, and the functionality is very limited at this point, but the potential is huge: imagine sorting readers by profession, or imagine seeing a person’s picture beside comments, or having the functionality to sort comments by readers etc. To view the front page widget in action, and to see an example of a nascent community, visit Fred Wilson’s A VC and check out the widget box on the left side of the site.
