@Reyn,
We aren't going to follow the forums for feature requests and answers, as we'd like to use the site for our own personal use eventually instead of being here for "work".
We are going to launch a blog that will have any answers we can give on any of these subjects and if you want to get something to our attention then contact the webmaster department of the help desk.
As to the polls, the current plan is to import the old poll data as text in the body of the first post to provide the context back for those topics (many of whom make no sense without a poll). We may make a new poll feature but would likely make it quite different than the way previous polls used to work and this is low on our list of priorities right now.
