The Mechanical Moo-Lah?

BoomTown has officially selected The Mechanical Zoo–a super-secret-shhh-onthedownlow start-up that already got tons of attention due to its passel of ex-Googlers and its mashup plan to mix social and search–as its next candidate for excessive Web 2.0 funding. And, according to several sources, the San Francisco-based company is working on closing a mega-Series-A round right now, with all the usual big VC suspects in the running. The Mechanical Zoo has already raised $750,000 in seed funding from angel investors and has access to other funding from institutional investors.
