Quora is a collection of questions and answers created, edited, and organized by everyone who uses it. The main goal is to be the best possible resource for someone who wants to know about each question.
I had joined Quora when it first became online (January 4, 2010) and have not really used it much. The other day I was stuck with some technical issues over on WordPress and asked the question on the WordPress forums and then on Quora. I got a reply in less than 8 hours from a seo expert on Quora. I learned over on Twitter where I thanked him that he is located in New England.
Quora is like other social media websites where you can include your bio and links to your other social media accounts and follow people.
