WTH are Aardvark, Hunch and Quora?
Hunch is basically a diagnostic type site. So you say you want a computer...and it gives you 20 questions with each question narrowing down your solution. Do you want a laptop or netbook? Do you want it in black or red or blue? etc.
Quora is basically a regular Q&A site mixed with twitter and Facebook. So you can follow a topic or a question etc. Personally I found it a bit confusing.
Au contraire, Aardvark was built so you wouldn't have to spam your friends. Each user of Aardvark puts his field of expertise in his settings and only receive questions Aardvark AI thinks a user can answer and it gets better with time. It's really brilliant, and it doesn't ask your friends only, it asks anyone in the community that may be able to answer your question. It's a fast way (by IM, twitter, email etc ) to ask and get answers without bothering people who don't know anything about your question.
Disclaimer: I don't work neither for Vark nor for Google. But I think it's a great service.
Me too, but then I replaced 'software engineering' with the language I really know and I now I can answer most questions I get.
If I say I'm an expert on "linux", that could mean linux kernel code, the LAMP stack, or administration and then I get questions like "why do I not get sound out of my netbook on Ubuntu 9.10?"
