Topix.net, the algorithmic news engine, has recently added 15,000 weblogs to their topical news feeds and search results. Algorithmically the blogs are on equal footing with the traditional news sources at Topix.net.

Rich Skrenta also discussed how they arived at 15,000 blogs and compares the number of blog channels vs mainstream news channels on each topic. Interesting that few bloggers blog the local and sports themes as compared to the mainstream news. From the 15,000 blogs tech blogs outweigh tech mainstream sources by a factor of about 6 to 1.
