Think of a question, any question? OK, got it? Now download this app and do a quick search of its database and the chances are that someone has answered it already. That's because Quora is essentially a big community that matches curious people with smart people to create a huge database of questions and answers.
Previously, iPhone users had to rely on Quora's mobile optimised version of its site, but this app provides a slicker and faster way to access the service. New features include the ability to search the database for Q&As related to your current location and a time-killing shuffle options that throws up random information to keep you entertained.
Quora has lots of interesting content that goes far beyond the usual random tit bits of information that you find on other Q&A services. It's definitely worth a download.
