I spent the past six months as an intern at a company that practiced a mix of scrum and XP methodologies and learned how important getting feedback is for the success and direction of a product, so I'm asking every bright person here for any examples or ideas in integrating in a feedback system for a web application. I like twitter.com's system [http://twitter.com/help], but that is simply to request to get help. What about a way of allowing for user suggestions? My only concern is that it could easily be "overdone" and draw away from a clean and usable site.
