For an online tool meant to answer questions, Quora sure has raised a bundle of them.
Among those questions: What is it? How is it different from other question-and-answer sites, such as Yahoo Answers,Formspring? If anybody can edit it, doesn’t that make it similar to Wikipedia? And, most important, what can I get out of using yet another social media tool?
Still, a growing group of social media experts and communicators say Quora is and will be as useful as Twitter.
