Aardvark was the best Q&A system I've ever seen, felt like the most miraculous thing I've seen in my life. Sadly I've only learnt about it from the news when Google bought it and in just about a year Google closed it. It worked like this: you just write (on the website or in ICQ) an question (in whatever a form on whatever a subject, no limitations or rules, just avoid offence), it gets routed to a number of semi-random people all over the world (you included for the other people's questions, once you receive a question you can answer it but there is nothing to encourage or discourage you, purely voluntary, and nobody but the question author will see you answer), you receive the answers (you can also answer an answer to thank/feedback or ask for a clarification). Everything was semi-anonymous, you were not forced to disclose yourself. Unlike Quora Q&As were not recorded (openly at least). Unlike Quora, whatever you ask (whatever a question you could imagine) you would always receive at least some useful and interesting answers in minutes-day (and could request more if not satisfied). Unlike StackExchange you hadn't to bother with boring rules, the format was just like asking a good friend that knows everything and enjoys answering your questions. I've ran out of questions my imagination could supply back in the days, now I have much more but there is no Aardvark any more :-(
