Long time lurker, first time poster. I'm going to be going to a school-sponsored 48-hour hackathon/startup competition this weekend and am planning to pitch my startup idea in hopes of getting some feedback (and, hopefully, assistance) with it. I've discussed my idea with many people in the past, but have never had to pitch directly to other developers. I know it ultimately comes down to getting other individuals interested in your idea, but does anyone with more experience in the matter have any tips or suggestions to give me an idea of what to expect/make me feel more at ease?
