There is a new site, Blogsonar, taking a unique approach to blog indexing/promotion: Visitors can register, log in and post a review or other blurb about their own blog such as the one I wrote about Colloquium. In exchange, the author reviews Blogsonar on his/her own site.
The layout is attractive, the site is easy to navigate and, although there is not a lot of content yet, there is a variety of information available. It has the potential to be a valuable resource as more writers discover Blogsonar and contribute content.
