You may have heard of Carson's web design company Carsonified from some of their previous projects including starting the Future of Web Apps conference and the Think Vitamin blog and podcast. Carson talks about his personal history and starting his company. He goes over the concept behind Treehouse which turns learning programming into a game where you level up and receive badges for completing. Carson also talks about an interesting concept for career planning for your employees.

At Web 2.0 Summit 2011 Kevin Rose shows off his new company's first app called Oink. It's centered around rating things, no places. It's a way of seeing what's a popular thing to try or eat at a given place. People can become experts in a field by checking into that thing more often, and vendors may be able to give deals to experts in their company's field.

This time on Foundation Kevin Rose sits down with Dennis Crowley, founder and CEO of Foursquare. Dennis chats about how he got into technology, how Foursquare got started, how to approach building your own start-up and much more!
