I don't like how polls have been made into a separate thread type. A poll should be an option for a discussion, an article, or a question. I can't even count how many articles I've read for many years where a poll has been included. Granted, the "poll" thread type is simply a discussion with a poll on top, but that still prevents it from being used in articles. It makes a little less sense in the question thread type, as the thread type itself is already an up- or down-vote.
If polls could be split back out into an optional part of discussions, articles or questions, that would be best IMHO. And give us the option to put the poll at the top or bottom of that discussion/article/question.
