Featuring questions and answers that come entirely from users, Quora is competing for the title of one of the biggest knowledge bases on the Internet. The team responsible for Quora actually compares it with a cache for the research people do when trying to find information online, and for all the questions and answers that go with one such process. All the data that is consigned to Quora becomes instantly findable and usable by others.
And it also becomes further expandable. If the information contained in any Quora page becomes obsolete and needs to be reviewed, then anybody can do it. In any case, it must be mentioned that every question has a revision story attached to it, letting others know everything about the one who has updated anything.
Besides, questions on Quora can receive multiple answers. The idea is that the best ones (as determined by users) are featured on top, so that those who stumble upon any Quora page can know where to look for the best answers if time is running short.
