«A continually improving collection of questions and answers created, edited, and organized by everyone who uses it.»
«Quora is a simple question-and-answer site. Whatever your question, type it in the search box and, if there isn't already an answer there, users will pile in and attempt to answer it. Information is organised more like Wikipedia than Google, with answers prioritised by how useful they are, but the site uses Twitter-style following to track the best contributors. (Guardian)»
