There was an unlikely guest among the techpreneurs at the Web 2.0 Summit in San Francisco: M.C. Hammer.

He made an appearance at the conference not as a celebrity in parachute pants, but as the brains behind the up-and-coming Web search service called WireDoo.

The rapper-turned-entrepreneur described this new service as a search engine that provides adeeper type of search“, adding information on possibly related topics to queries. If you were to search “car” for instance. WireDoo might return results about insurance, pricing, and consumer safety ratings. Its tagline is: “Search once and see what’s related.”

Other details about the product were scarce.

Hammer claimed that WireDoo, which has been two years in the making, is not trying to compete with established search giants like Google, but hopes to offer a new type of search, a search that will render not just direct results.

The project, which Hammer said he has a team developing, is still in pre-beta. Its website is currently letting people sign up to test the search engine when a beta release is ready.

Cool. Can’t wait to ‘WireDoo’ “how to do M.C. Hammer slide”.
