I understand the decision from a business point of view, but it's a shame when taken in context to political discussion in general.
So many people I know only get the political news and discussion from an echo chamber on one side or the other. I rarely posted on the Politics forum and only checked out the forum on occasion when I wanted to learn more about certain key issues, but I've told a few people I know (who were displeased with their political news sources) that the NeoGaf politics board is cool because they let both sides talk freely. It was great way to see both sides of the argument without having to walk on egg-shells or wade through complete shit like on 4chan. And if I or someone else says something that is kind of out there, then instead of being banned, you would instead meet the responses of other users. Speech vs speech.
But again, I understand the decision. It made sense to let everyone talk more freely to build the site back up, and now that it's gotten bigger, things need to be cleaner and more presentable.
