I'd love to be able to post polls that users can vote on.
I'm thinking of this in the context of @Andy's post about "Community Founder" as a visible rank; a yes/no vote would be great for support features like this. But they'd also be great to gauge demographics.
For example, in the topic "Building and Managing a Website":
What are you using to build your website?
> GoDaddy Website Builder
> Another Content Management System
> Just code
That would give everyone a better idea of what products our community is using, which will be really helpful when giving advice. Just a thought!
