Awesome idea, I plan on adding in all my polished examples soon, and probably polishing up some of the more simple ones and sharing them, too.
A question/suggestion: is there any way to group together similar examples? For example, there are many ways to do an on-screen keyboard, some more suitable than others depending on what people want out of them. I foresee a lot of duplicates or similar examples being posted, but if we could have a way of adding additional examples (with their own author and description) to an existing one, that would help to keep things clean.
