Today at the Web 2.0 Summit, Ballmer announced that we are opening Popfly to a public beta today! It is a completely free way to build really cool Silverlight based mashups. There are tons and tons of pre-built components from Twitter, to Virtual Earth, to Flickr.. I can't wait to see what you build..
Here is the cool little game I built on stage at ReMix Boston..
If you build something cool, drop me a line, I'd love to hear about it!
