One of the best things I learned about WWDC is to not be shy about signing up for labs.
Don't hesitate because you're not a big company/app.
Don't hesitate because you think your code isn't "good enough".
Don't hesitate because you're not thrilled with how your app looks.
DO IT and you can get such good feedback and/or knowledge.
One of my favorite labs was when I told the Xcode team "I'm sure I don't use 10% of Xcode's features. Please show me cool things." and they did!
