Well I haven't really used this page for much. Just recently I put together a "Hackintosh" system, and have been familiarizing myself with Xcode. As an initial project, I'm planning to create an OS X application called "Grade Keeper." I actually wrote this same app in college about 9 years ago in Visual Basic as a project for my Human Interface Design class. I'm completely new to objective-C, so learning the syntax will take some time. Overall, I do like how well put together Apple's developer site is. They have plenty of examples and articles to get your going. It's the best knowledge base I've come across yet for any development platform.
