Great quote from Steve Case: "We attract the world's most talented young people here, give them a world class education and then send them home to compete against us," he told Inc.com. "It makes no sense."
Hey, adriannica - check out my comment above for some of how we create the list. And here's a bit more of our methodology http://www.inc.com/30under30/2011/how-we-made-this-years-30-... (although mostly it involves lots of reporting and much internal debating.)
Well said, zaidf. This is Christine, one of the editors and writers for the project. At Inc., we largely focus on small, fast-growing companies, needless to say, pre-IPO or sale. And the names you'll see last year our list (LivingSocial, Foursquare), and previously (Modcloth, Mashable, Aaron Patzer, Mark Zuckerberg) won't appear on the list again. There are simply too many innovative, fascinating new, younger, companies each year for us to explore and profile to repeat names. Hope that makes sense.
