Hackathons are fun and productive when what you need to do/learn — something you haven't already done/learned — can be done/learned in a weekend. Once you graduate, there's a lot fewer of those things lying around. Quote:
> We need look no further than the "hackathon," that sad facsimile of the days when we were all learning the basics so fast that the world could be ours with just a day or two of focused effort. Hype up an exciting atmosphere, assemble some folks with so few attachments in life that they have time to spend all weekend at a hackathon, and this ritual will summon up the old gods. The hackathon is the proof that people believe this can work, and it is the proof that it doesn't.
