Forget all this superfluous nonsense. Listen to your inner instincts, Cocoa Developers. Stop making software and start making artwork. Have *fun* with your software. Your software's function/purpose is not separate or merely 'connected' to your User Interface, they are one and the same. Make your program appealing, make it interesting, make it useful, make it *easy* to use.

I guarantee, if you write the kind of program YOU would have fun using, chances are, others will like it too. Unless you're a really hardcore nerd in which case you should not be programming with Cocoa in the first place, go write a webserver in assembly or something.
