Tim Berners Lee blogs about blogging and highlights something that is indeed becoming more visible every day. Blogs provide filters for the web and a certain level of trust as well. Multiple initiatives that are rooted in the blogosphere are making this trend even stronger.
“A great example of course is the blogging world. Blogs provide a gently evolving network of pointers of interest. As do FOAF files. I’ve always thought that FOAF could be extended to provide a trust infrastructure for (e..g.) spam filtering and OpenID-style single sign-on and its good to see things happening in that space.”
