"Glitch is a massively-multiplayer game, playable in the browser and built in the spirit of the web. It is currently in development and will launch late in 2010. Private alpha is beginning shortly and a public beta period will begin this summer." Exciting!

Daniel Terdiman interviews Stewart Butterfield and Cal on Glitch, which is what Tiny Speck are making. Good interview, and worth noting just how often they threw things out.
