They are basically interactive surveys. Users can submit ideas, link them to other ideas, and then those ideas can be voted on. It's an interesting way to find points of consensus and difference of opinion.

The downsides are obviously that setting one up requires some level of effort and you need buy in from the comunity you're looking to understand. The end results though can be pretty cool in that you can use network analysis techniques to see how support for different ideas are linked.
