Google For Blogs
Google Blog Search – I tried it a couple of times, my search results seem “weird”. Oh well, it is in its beta state (like almost all Google services). I’m sure this thingy will get better. And if you don’t like Google’s search result layout, try Blogger Search (also in beta), they return the same results but in different layout. For those who are still in the dark, Google owns Blogger, go figure.
