Google Has Blog Search Engine

U.S. Internet portal Google has launched a search tool for sifting through Web logs, the Washington Post reported Thursday.

Google Blog Search is expected to be followed by similar tools from Google competitors.

The so-called blogosphere is growing. In July, 29.3 million people, or 20 percent of active U.S. web users, accessed blogs or blog-related sites, according to Nielsen/NetRatings.

That number represented a 31-percent increase since the beginning of the year.
