They believe everyone’s an expert at something. So they are trying to do something really simple – showcase what you know and connect you to experts who can give you great answers. Connect them to your Facebook or Twitter and they will figure out what you’re truly interested in, the topics that intrigue you, and the questions they think you’re the best person to answer. If you use Facebook they can find the friends in your network that are most qualified to help answer any question and give you full control to ask away. If you have a question for an expert, they will find the right folks who can give you a great reply as quickly as possible. Ask, answer, get recommended and get recognized!
