TechCrunch reports startup search engine Blekko kicks up a $30M investment from Yandex (YNDX -2.2%), helping land its CEO, Arkady Volozh, on Blekko's board. It's an interesting move from the Russian search engine - still reeling from an ill-fated meeting with hedge funds yesterday - that lines it up to compete in the U.S. market with Google (GOOG +0.2%) if Blekko can actually turn rave reviews into significant levels of search traffic.
