Blogcosm is a metablog. It's a blog about blogs. At its core, Blogcosm is strictly about the data. It's a reference site which aims to get to the bottom of what's going on in the blogosphere and all the data circulating around it. You'll find lists of the top blogs in each of their respective categories, e.g. arts and humanities, business, entertainment, etc. There's a people index, blog profiles, events, and categories. Information is compiled from sites like Technorati and Alexa. The site has its own blog which endeavors to sort out all the underlying trends and happenings within the blogging world itself. Blogcosm covers a lot of ground; it focuses on all aspects of blogging, not simply tech-geared blogs, although there does seem to be a greater emphasis there. The blog has its work cut out for itself. There's still much to be done, but, it's a good start.
