MC Hammer’s latest catchline is “Search once and see what’s related.” But it’s not a song line, it’s a business proposition.

Yep, MC Hammer is launching his own search engine, WireDoo. The selling point is that it goes deeper than the rest and isn’t scared of multiple relationships. And no, that’s not innuendo.

Speaking at the Web 2.0 Summit event in San Francisco, Hammer (aka 49-year-old Stanley Burrell) didn’t really go into a lot of detail, but said WireDoo will be much more about figuring out the relationships between specific keywords and the various topics that relate to the search.

He also said that results pages won’t just give a list, but rather come up with results for different contexts such as local information or online retail. That sounds remarkably like the way that Microsoft promoted Bing, so it’s tough to figure out what’s revolutionary here.
