Stackopedia

Stackopedia helps improve your culture by feeding you with notions on arguments of your interest...or, why not, on fields you never explored before.

This app feeds information from Stack Exchange, a network of Q&A communities each focused on a specific field: users can post questions and answers to other user's questions, vote them, and accept answers for their own questions.

Every time you run Stackopedia, a high voted question from one of those communities get chosen randomly and displayed with the best answer available. And as you can choose from which communities the app feed, you can either improve your knowledge in a specific field or learn something completely new.
