I keep trying to find new way to track the Blogosphere. While Technorati remains my personal favorite, check out Strategicboard.com.
The Israel-based company positions itself as being a Web 2.0 search engine that aggregates IT related RSS feeds. They automatically monitor and identify new IT related blogs, and currently track 20,687 technology blogs with 847,944 technology related posts indexed.
They do a very good job offering a simple interface with highlights of tech related blogs, plus a listing of the Top 100 Tech related blogs.
