Google launched Google App Engine, a plattform to create and run web applications. Google App Engine is currently in preview release. On time it’s only Python-based supporting Django. Other languages may be supported in the future.
HuddleChat, one of the sample apps for Google App Engine, is critisized being a rip-off of 37signals’ Campfire.
Google decided to take HuddleChat down. This was a reaction to some complaints from the developer community. (via)
