Great for these guys to have their event sold out! (Though... the justin bieber comparison is a bit disingenuous, but hey, i clicked the link so it worked.)<p>Here's a question: for companies that sponsor hackathons, do you find value in doing so? That is, are you able to measure the effectiveness of that channel from the perspective of making more people use the product, recruiting better-quality candidates, or anything else to help the business? How do you even measure and track the value?
