Good input. As a college student as well, I wouldn't expect any of my peers to attend something like this for free either.
I believe the key to this, however, lies in a good business model that pays the students for their time and input. Many students are strapped on time, but I'd be willing to wager even more are strapped on cash.
Ultimately, my concern at the moment is not whether students would be interested, but whether startups would be interested. What do you think?
