"Your Sponsors who give away the coolest prizes". Primary motivation for most hackers to spend this weekend at a hackathon I know is to win the prize money/gadgets.
I disagree. At a competition like PennApps or Disrupt, your odds of winning anything are really small. Most people I know know this, and just go to have a good time.
I actually tried to submit it before "martinoma" but was told that I was submitting too often. It's hard to say if TC really did submit its own story - throwaway accounts are quite common nowadays.
Admittedly, I did decide to submit quickly so that I (might) reap the upvotes--HN has been transfixed by Aaron Swartz, and reasonably so, and I thought that people might like a reminder of how the community reacted a few months ago.
