Which search engines hunt content in blogs?

A specialized blog search engine is not always the best first approach to finding the hot blog. For example try a web search with something like best book blog or best technology blog or best science blog and explore your results. On the other hand if you wish to search the content of what folks are writing in their blogs, blog search engines are essential. These specialized search engines update their search databases at least daily whereas large search sites such as Google are updating just once a month.

Blog search engines include: blogsearch.google.com ; technorati.com ; www.pubsub.com/ ; www.daypop.com/ ; www.feedster.com/ ; www.icerocket.com/ ; www.blogpulse.com/
