Stewart Butterfield founder, Tiny Speck and Glitch

In 2008, when the Flickr co-founder parted ways with site parent Yahoo, he headed home to Canada to ostensibly take some time off. One year later, Butterfield, along with four Flickr veterans, launched Tiny Speck, a Vancouver gaming company. The first product, a giant, online multiplayer game called Glitch has been the buzz of tech circles for more than a year. And those who scored an invite to test the game are delivering rave reviews. Some say it could become the next World of Warcraft when it’s released to the public this summer. Could Butterfield take on Zynga’s Mark Pincus?
