I think the site is great right now, one idea that I had that might be a bit of fun. Would it be possible to post a survey question with 3-4 options for the answer. The BBC site does it occassionally and sports.com used to. It was a great way to judge opinion on intersting topics that go either way. You could do one about every 2 -3 weeks and see how opinion goes.

NOt sure on the technical side of it, shouldn't be too hard, you have to be able to count votes and then update stats, usually you only get to see the stats if you submit a vote
