Kevin's last blog post on BartRage.com inspired me to bring up GetSatisfaction.com.  It's a user-powered customer service forum when customers and company and organizational representaitves can interact and share their experiences.

Transit is an important part of people's lives, and its users talk about it in many different aspects.  GetSatisfaction.com seemed like a way to expose some of those conversations, find some of the most useful suggestions which might otherwise never make it to decision-maker's ears, and stop the same questions from being asked over and over again.  In short, it seemed a perfect fit for transit.
