Hey, welcome to CD! I love the Hank Green quote.
I came to be on the website team out of equal parts boredom and interest. I had some pretty strong ideas about what we could do with the site, and I had four hours of summer school to sit through every morning (AKA website editing time)! So I'm a strange case, but I think a good place to start is to see if anyone on your team has experience in HTML or CSS (I don't, but now I realize how useful that would be). Does anyone know a lot about your team history? Helps organize the team? Reaches out to sponsors? If no one is just interested, you could call on these people to help make your website useful and beautiful. They all have something to give or gain from a good site.
And if that doesn't work, make the freshmen do it.
As far as general recruiting, I'm not really in a position to give advice until I see if our strategy this year worked. I'm crossing my fingers...
