Wall Street Journal’s Vauhini Vara has a nice round up of blog search engines including Feedster, Technorati and Icerocket. I found it intriguing that she did not dig into the subject of what happens to these “Wannabe Googles” when the big three launch their blog search? Or perhaps how ineffective these search services really are! Talking about the big three, a little birdie told me that Yahoo RSS/Blog Search could go live (or beta, since Google had made beta the new black!) before baseball playoffs. Still trying to confirm this one!
