At first I was going to put this post under the "search engine" category, but I feel it fits better here in the SEO category becuase of the great tools it has. Anyway, have you all heard of Blekko? They were discussing it this week at the SMX East Expo in New York. If you like toys, read this post with a few thumbnails in it. This screen shot alone says it all: I'd love to see some intelligent comments (here or on the blog). It is dofollow comment!
