I've set up a subreddit, Polit, largely as a result of the ham-handed banning of widely read political sites by the existing /r/politics subreddit. I don't have any illusions that it's going to be comparable to /r/politics, and people advocating the removal of the bans there should continue to do so. But I've started by posting articles from sources banned by /r/politics. I'm going to be moderating as loosely as I can without being overwhelmed with net vandalism.
I'm seeding the site with articles from the banned sites, both from the left and the right, because as a progressive I think it's important to look at interesting articles from all parts of the political spectrum.
