Google Announces Google App Engine

The highlights for now:

• Python! *Squeeee*
• No C Extensions (boo! understandable, but still boo.)
• WSGI!
• Django!
• Google Mail, Apps and Accounts integration!
• BigTable™
• FREE!
• Did I mention Python and WSGI?!

I've got to go change my pants now, but I'll post my extended thoughts later. I'm furious I didn't hear about this sooner and get one of the initial invites. WTF internets?!
