We need a Wikipedia-style knowledge base on all topics so the information can be organized and can evolve and improve over time.

This way noobs (like myself) can get very good information about how a function works and see examples of it in action.
Maybe people can even rate how good the explanation is so we know which ones to improve. This will significantly decrease the barrier to entry for new programmers, which will lead to a larger Zorro community, better ideas, and in the end, more money for everyone! (Well at least the smart ones).
