I'd love to see a widget developed that brings the functionality of this very idea forum to WP, without having to sign up for a 3rd party service like UserVoice. The widget would integrate with native WP user profiles, for a single sign-on experience. Ideally I would love to see this integrated with BuddyPress as well, but hey, I'm on food and shelter here...;)
Does it already exist? If so, I apologize! If not, you would be my hero(s)!
