Is hiring software developers an evaluation problem or a supply/demand problem?

GitHub provides a great signal for evaluating whether someone is one of the top 100 or top 1000 developers in the world. Just check how many follows or forks they have! But Linus and DHH can work wherever they want, and they're probably unlikely to work in SF for $60--100k plus options in your SaaS startup.

Because of supply and demand, the people who are going to work long hours in that price range seem to be recent graduates. As a result, all of the hiring processes I've seen are geared toward trying to get a vaguely passable evaluation of how good a recent graduate is, using the minimum possible developer time. This leads to the coding interview as we know it: 30--45 minutes long and usually involving a trite programming problem utilizing the most advanced class most undergraduates will have taken, introduction to algorithms.

Personally, I would love if tech companies switched to evaluating based on work samples (e.g., code), but I don't think it makes sense given the demographics that they're targeting as new employees and the amount of time to have a developer genuinely evaluate a coding sample (rather than count followers, etc.).

Is it likely that GitHire and similar will increase the supply of good candidates in the right price range, rather than periodically e-mailing the top developers on GitHub and possibly polluting the ecosystem?
