Quora

Quora is a super useful social network that can help you find the answer to a bunch of questions in just a matter of seconds. In fact, you'll find an entire community that's ready to answer any question you may have at any time. Enjoy accessing a wealth of information on all kinds of topics as you expand your knowledge on practically any subject.

The first thing you have to do is select your fields of interest. That'll grant you access to already answered questions related to those topics. Once your list of interests is set up, you'll see a TL full of topics and questions already posed by the community. Using Quora is very easy. Ask all kinds of questions that other people have already answered, or answer them yourself. If you want to find out the answer to a specific question that isn't already posted, Quora can help by publishing your question for thousands of users all over the world to answer.

In order to ask a question, simply type it into the section provided.

Once your question goes live, it's posted to the timelines of other users with shared interests that follow your chosen subject matter. In a few seconds flat, your question will be public for the world to answer. Similarly, you can weigh in on other users' newly posted questions.

Quora has a whole platform full of users with diverse, curiosity-piquing questions and is a fairly decent source of information. Once you're on Quora, you'll probably never again go to bed without learning at least one new factoid.
