I like it. I agree that there are limits to what can be accomplished in such a short timeframe, but there's plenty of work that could fall within those constraints. I'm often asked for opinions that don't involve code at all, just an overview of the tech that's out there that could be applied to a given problem. That sort of thing could easily fall in to a couple hour time frame. It could be the twitter of freelancing. :)

Oh, and to veer back to being on-topic, I'd likely use it and I don't know of another service like it.
