Our friend to the north, Marcus Nelson (the guy behind such things as hyperlocal site Citizen Wausau, and co-working space Citizen Desk) is involved in the launch of a new product/site, it’s called UserVoice.
The idea behind UserVoice is that trying to talk to your customers and users to find out what they want is too difficult to manage using things like email and forums, so why not leverage the idea of a collaborative site where users vote, similar to Digg, so that the common and popular issues float to the top.
They have an example site at example.uservoice.com you can look at to get an idea how it works, or even better, take a look at uservoice.uservoice.com and see how they are eating their own dog food.
If you’re dealing with user feedback right now using a forum, or trying to manage email requests, this thing looks like an ideal replacement that would be 10 times better for all parties involved.
