This and the other startups like Interview Street seem to be focusing on the less lucrative side of the hiring problem. Like Joel Spolsky said, and like I know from personal experience, my best developer friends aren't in the market salivating to take interview tests, and do code sprints to prove they are good. They are passionate about developing, have many great jobs to pick from at a given time if they tried. If they have free time, they would rather put it on an open source project that excites them, or a smartphone/web app that they are making for themselves.

If you look at filtering mechanisms themselves, there are companies that try to have puzzles that they ask you to solve before joining (eg: ITA software). But they are really challenging puzzles that I would solve just for fun anyway, (which is what I did for months till I one day decided to apply for a job there). The fact that these puzzles are also made by the company (and not a third party website) makes a difference. It tells me about the people that work there and potentially about their culture. On the other hand, building a random web app to prove basic skills is not something I would imagine most talented web developers would like to do anyway.

If you look at it from the perspective of a company that is hiring, tools like this solve merely one part of the puzzle. It takes the subset of developers who are already in the market for a new job and filters them. As a startup though, what I want to do is lure the great engineers who are content at their regular jobs and not looking at all because of inertia. It sounds like there is more of a "search for developers" problem that will expand the breadth of all the developers available to me, instead of focusing on the ones who are already out there (and are most likely not the cream of the crop by definition).

In short, I don't mean to be negative, and am not saying that there might not be a market for a tool like this. But I am pretty certain that if you are a great developer, you don't have an incentive to make a web app on this.

I agree with this 100%. Coding tests and filters like this make sense when we have a market with an oversupply of developers that need to be filtered out. Right now, we're in the opposite situation with more jobs than skilled devs.

I think a few companies (Google, Facebook, Twitter, etc) have more applicants than open job reqs, so for them these types of products have value.
