This week we talk to Joel Spolsky, the founder and CEO of Stack Exchange and Fog Creek Software -- and one of the creators of popular organization app Trello, which just hit 7 million users. Spolsky tells us about the origin and design principles of Trello. A former Microsoft employee, he tells us how he thinks the company is doing at turning itself around. And he dishes on what happens when unscrupulous VCs take over startups.

Plus, we tell you what to think about Pinterest banning affiliate links, Facebook cracking down on names it thinks are fake (even if they aren't), and cloud company Pivotal changing its strategy on Hadoop.
