What Is Aardvark?
Aardvark is a network of users who answer each others questions. It opened to the public in March 2009, but new users must be invited to join by existing users.
Users register as “experts” on at least three subjects. I selected:
Basically, someone sends a question about HTML to Aardvark, which eventually gets routed to me. Then Aardvark emails me the question, asking if I want to answer it.
Of course, there are many more options. I can limit questions to “friends” or members of groups. I can also receive questions by IM and chat services. iPhones will be supported soon.
Does It Work?
I don't know yet, because I have not sent or received any questions! I think I need to register for more subjects. I am also used to asking questions on Web forums, however I will try to ask my next question on Aardvark.
Aardvark is a brilliant idea. I will report back on it, when I have more experience using this innovative service.
Update
Google bought Aardvark on February 11, 2010. Google closed Aardvark in 2011.
