Thanks to some travel I'm a little late to the party, but I was tipped off by Topix.net CEO Rich Skrenta (entrepreneur, NU alum) that, Topix has added blogs to its news mix. Topix automatically tags/categorizes content coming out of continuously updated sources like news feeds and provides search against those labeled chunks.
One of the interesting things about Skrenta's post is his analysis of how much crap there is out there in the blogosphere. To summarize, 90% crap approaching 95% useless, e.g. not frequently updated.
Let's see if I'm in the Topix index.
