WSJ.com - Google Launches New Tool To Let Users Search Blogs "Google's blog search works in much the same way as Technorati, Feedster and others, but there are some differences. For Google, the default is to rank results by relevance rather than by the most recent entries. (Google also allows users to rank results by date.)
While Google was slow to enter blog search, the industry is still nascent enough that the search giant has the potential to attract users who have never heard of Technorati or Feedster. "It's going to be a real challenge for some of the small players to fight back," said Danny Sullivan, editor of SearchEngineWatch.com."
