Quora is the best website if you want to get your questions answered in best way possible. I have been using qoura from about one year. I am having an amazing time with quora. Its feel extremely good if you are answered by good people around you.
You can ask questions of any category and request people in that field to answer your question.
This is a good alternative for social networking websites.
One can also create a follower base, for people who follow you.
Atlast I would say, quora is not an information website, it is just like a forum, where people ask questions and other people answer them. And it is worth a try.
Thank you.
