I think it would be a great idea given the nature of talk on these boards to have an opinion polls section where people can register their votes on a said question and see the results displayed in a simple bar chart or graph.
Lots of sites do this and it gives a simple and quick overview of opinion about an topic
For example just off the top of my head, have a look at the poll on the right hand side of www.itv-f1.com
(this is only an idea, im not saying that the graph should look exactly like that) but its a thought!
