Blekko is a search engine developed by Rich Skrenta, the founder of the DMOZ web directory. In order that you might enrich your minds, and perhaps learn something new, can you tell me the ways in which Blekko differs from the Google search engine? I'll give a month for this one. In the event that answers were attempted, I will choose the Best Answer on December 4. Remember, there can be up to two Best Answers. By the way, copying or even paraphrasing Blekko's About page does not make for a Best Answer. Include some things that are not on its About page.
