I was about to say "talent acquisition" but given they're keeping the tech it's probably not the right term. But the price point seems likely to be about that of a talent acquisition.
This seems like a win for everybody: Infochimps gets to build its business, YC-funded founders get to exit profitably and move onto another project, Paul Graham & Co. claim another successful start-up, and YCombinator's share of the buyout money can fund more start-ups.
Infochimps is bringing in the DataMarketPlace user base and community to expand its data sources and resources exponentially. This is only the beginning of what Infochimps could be. :)
