How to collect customer feedback? [closed]

What's the best way to close the loop and have a desktop app "call home" with customer feedback? Right now our code will login to our SMTP server and send me some email.

Why is it important to close the feedback loop?

Closing the feedback loop in real-time helps brands maintain revenue, protect their reputation, and make their customers feel that their feedback is valued. Also, it can help brands remain competitive in industries increasingly driven by CX performance.

The site GetSatisfaction has been an increasingly popular way to get customer feedback.

GetSatisfaction is a community based site that builds a community around your application. Users can post questions, comments, and feedback about and application and get answers to their questions either from other members or from members of the development team themselves.

They also have an API so you can incorporate GetSatifaction into your app, and/or your site.

I've been playing with it for a couple of weeks and it is pretty cool. Kind of like stackoverflow, but for customer feedback.
