Long gone are the times when the site attempts to allow a diversity of viewpoints. The whole benefit of something like reddit was that it allowed discussion about complicated topics, with a system that would naturally allow the "best" opinions to matriculate into view. The problem is that they have been inundated with censorship based on the sensibilities of their most sensitive, lunatic fringe.
Instead of drawing a hard line, the admins and moderators have reliably caved to the demands of this vocal minority at the expense of freedom of expression. The result is a substantially worse site with each month. I imagine that there will be a DIGG-esque migration away from the site as soon as a decent alternative presents itself.
