My first introduction to GetSatisfaction came through Flex My Day, and it all looks pretty cool.  The company/service is all about providind a medium for companies with large consumer bases to get in touch with what their clients actually want, which I guess would represent a pretty big investment for a company to figure out and build such a service for themselves, and is probably no small part of GetSatisfaction's success.

For a company like where I work our clients don't really fall into that category, so I can't see us being interested in the service, but there's some pretty big names on their roster.  The developer tools look pretty cool, and coupled with Flex My Day's Flex class libraries, I imagine it might be a cool base to make some sort of customer feedback AIR tool-thingy.
