Is getsatisfaction.com a knowledge exchange competitor of hosted stackoverflow engine?
DISCLAIMER: I have no professional/financial affiliation with getsatisfaction.com or stackoverflow.
GetSatisfaction is more centered around customer support for a company.
That meaning, you have people for the company there. And users can ask questions about the product the company has.
You can see a great example of GetSatisfaction for Adobe's version of it.
It has features like what the mood of the users are in a said question and others that make it more support oriented.
I can see where the resemblance is though.
No, it is more likely competition for Uservoice. It was even brought up on Uservoice that we should change to getsatisfaction from Uservoice.
