Downvotes, or as they called them "burying a post." Basically, in v4, they redid a large portion of the site, with many many bugs present, a UI that the majority of the users hated, and made it a better platform for advertising instead of making improvements to help the community. It was a problem that came about in part from them working towards making it something profitable (ala advertising) versus something the community built.
Here is a link on reddit that discusses it a bit more in depth than what I'm able to, since it's all second hand on my part.
Did away with the down vote or tried to take other steps with it?
