What's Caterina Fake's Hunch?After Yahoo bought Flickr from the wife-and-husband team of Caterina Fake and Stewart Butterfield in 2005, then-executive Jeff Weiner charged Fake with "building the next Flickr at Yahoo." It never happened — though one result of those instructions, the ill-managed Brickhouse incubator, did provide some entertainment along the way. Fake is now joining a New York-based startup called Hunch. "It is a consumer Internet application, it will have a lot of user participation, and it is more than a little fun," she writes. It is the next Flickr, in other words, or so she hopes. But not at Yahoo. Jeff, shouldn't you be asking for half of Yahoo's money back?
