Powerset never quite managed to launch with their natural language parsing search product. But they did give everyone a glimpse with a preview of search for Wikipedia. Not quite game-changing enough for Yahoo to buy or Amazon's Jeff Bezos to invest in, but just enough to get Microsoft to pay $100 million. Which is considerably less what Team Redmond would have paid for Yahoo's search business. Not bad for a company running on borrowed hopes and dreams. (By Intern Alaska, photo from Powerset)
