This is really exciting.
It'll be easier than ever to create scalable web apps. Choosing python seems sensible, I don't see what the fuss is about.
I'm sure Amazon doesn't mind though, they'll just continue to get all of this business.
I did just read that Python is just the first step, other languages will be supported soon. :)
not a big deal to most people... but from what ive read this seems more like a competitor to heroku/appjet than ec2/s3 as others have mentioned
but as a django user, i am pleased
