Go Cocoa! Go Cocoa!
Yaaaaaaaay Cocoa!

The big question you're asking yourself right now is hopefully, "What's so cool about Cocoa?", closely followed by "Do other frameworks have cheerleaders, or is it just a quirk of alliteration?".

So what is Cocoa? Well, according to Apple, "Cocoa is an object-oriented application environment designed specifically for developing Mac OS X-only native applications. The Cocoa frameworks include a complete set of classes, and for the developers starting new Mac OS X-only projects, Cocoa provides the fastest way to full-featured, extensible, and maintainable applications."

For many developers the Cocoa frameworks provide a highly productive way of writing Mac OS X applications.
