Tansey: My bad. We were crunched for time on Friday and I decided to launch the list on schedule while continuing to polish the copy. Think of it as editorial agile development...
As for the comments here about how we pick the list and finding good hooks and all of that, I guess I would simply say that we look each year to create a list with a variety of entrepreneurs who are doing creative things, building interesting companies, and challenging the status quo in their industries. Celebrated start-ups such as Foursquare and Posterous were on our radar from the get-go, but we were equally interested in writing about less showy companies such as the e-mail marketer iContact and the fabric retailer CityCraft. I think the result is a fairly unpredictable list; some people are very familiar with some of the companies, but I doubt that anybody is familiar with every company (SuperJam is pretty great, don't you think?)
Finally, for those of you who think young people are not particularly interesting, I'd recommend our regular "How I Did It" feature, or the section on our site devoted to serial entrepreneurs: http://www.inc.com/serial-entrepreneurs
