Jason Calacanis finally launched his human-powered search engine, Mahalo. The site provides about 4,000 curated results at the moment, with a goal of 10,000 by the end of the year. Points for a contrarian approach: the orthodoxy is that only machine indexing of the web can satisfy users' obscure curiosity; Calacanis says that doesn't matter because the top 10,000 search terms account for about a quarter of all queries. They're also the terms against which the majority of text advertising is bought. Anyway, enough of the boring facts; how did Valleywag do in the guessing game on Mahalo's name, purpose and backers? We're going to give ourselves a score of 9/10: Valleywag got most everything right, except we didn't know Elon Musk, the space entrepreneur, was in Mahalo's second round; and we fell for one Calacanis red herring, that the search engine might have some substantial podcasting element. That was a naive supposition: Calacanis may love the showmanship of online video, but he wants a private jet badly enough to go where the money is, which, in today's internet, is search.
