A web site that can allow people to submit and vote on topics on their street, region or state, their company or topics of interest? Something that can both work with the democratic principal and also for topics of interest. Wouldn't it be easy to link to (secure) data (google maps, addresses etc.)to make it valid and also to anonymous people on general interest?
Because you didn't build it :)<p>Go do it, it sounds like a good idea. There are poll sites that allow you to make polls on all kinds of subjects (a la HN polls but targeted towards a larger audience), but I think your idea would be a lot more useful.
Call it swingvote and allow people to create profiles that then show you (rough) demographic information.<p>It would be similar to those espn fangraphs(just more awesome).
