Not to degrade polls in any way, but they don't often add to the above reasons for being here. While I would love to chime in on which web framework is the best my observation is that:
a) the information I gain from reading a poll is minimal
b) the comments to a poll are less interesting than an ask YC link or a link to a story. The reason being that polls are (mostly) yes/no answers and tend to promote yes/no answers or flamewars.
Just my opinion of course. And since I come here to have my views challenged, feel free to do so. :-)
