Submit a question to Quora, a free iOS and Android app. Its user community will answer, edit, and organize a response. And you can blog about what you know about, too.
A Quora editor wrote to Forbes, "We are a continually improving collection of questions and answers created, edited, and organized by everyone who uses it. Over time, we aim to have each question page become the best possible resource for anyone who wants to know about the question."
