According to an announcement last week by blog search engine Technorati, their weblog search site is now tracking 50 million blogs.

As more and more weblogs come online and sites like Technorati.com and IceRocket.com get better at tracking them, these blog search engines will continue to be a great, growing source of people search and public record information.

So far, we have found three of the best blog search engines to be technorati.com, icerocket.com and blogsearch.google.com.
