I’ve been spending some time on Amazon’s latest venture called ASkville. I was chosen to participate. Probably many other people were as well so I’m not quite that special.
Askville is a place where you can ask a question about specific topics and other users will give you answers. You can rather the answers that you get, respond to the answers and start dialog with other people on Askville.
Not sure when it is coming out of Beta but when it does it is going to be a great site for collaborative information sharing.
Also when you answer questions you earn coins for another beta site called Questville. But that is still coming soon.
