Twice this week when I searched for a blogger's name and some other related keywords, I noticed that Google is running a little thumbnail alongside the first links. I have verified that this is not an experiment but rather a new mini feature. When I logged out of my account I was able to replicate it.
You should be able to see this for yourself on the following searches: Gigaom papers and Luis Suarez.
It appears to be in effect for WordPress blogs. See updates at the end of this post.
LATER:: If your blog is on Wordpress, then you get a thumbnail. This can also be found in a search for Scobleizer. Also, try Googling Jeff Jarvis or Kevin Mason blog and you will get the same result.
EVEN LATER:: There are further updates in the comments. Matt Cutts from Google notes this is a bug. Meanwhile, the images are popping up for some TypePad and Blogger blogs as well.
