The problem with human computation is that people actually don't really like solving those sorts of boring problems without good incentive. Amazon's answer, of course, is paying them for their work. I like von Ahn's approach better: Figure out a game people will enjoy playing that has the side effect of getting at the solution to your problem. I think the reason more people aren't doing this sort of thing is that game development is in and of itself difficult, and it's even tougher to make a game that gives you useful information on the side. Not to mention it's not clear where there's money to be made.
