APIs drive innovation

Facebook launched an API just 72 hours ago and there are already 944 registered developers, 117 discussion threads, hundreds of blog posts, and at least a couple of mashups: Facebook+Google Maps and Facebook+Bill Splitting.

I’m constantly amazed at how opening an APi to your web app drives traffic, buzz, and innovation.
