Hi Josh, You're definitely right. In the interview I talk about how the idea begun in the SitePoint Forums, then we started charging people to start a thread in the "Design Contest" section in vBulletin, then we spun it off as its own separate section of sitepoint.com with some basic software built around and only after we had proved that it was a sustainable business did we re-architect the software, improve the usability & interface, and then spin-it off as its own separate business in February 2008.
