I've been wanting to vote on polls for a long time. It just feels to me like that's the way K5 should work. When I first got here, it was until a year later that I found out that you couldn't vote on polls.
I remember I brought that up a while ago. Rusty did answer, and he said something like "anyone can suggest a poll, just go on IRC and do it", or similar. The thing is, I don't feel that's really very democratic, now is it? Most kayfivers won't get on IRC and have the chance to vote a poll down, but they will click the little button on their handy webpage.
What makes K5 great is anyone can easily submit and/or vote on a story. Since the FP poll is so visible, it should be treated similarly.
