I think forum's are still fairly popular. I hate the unstructured nature of some of the alternatives like reddit or Twitter. I'm supposedly the target demographic for all these newfangled platforms and I bloody hate them.
I know the shady figures that run this site are looking at ways to keep the forum alive. The issue is ownership and liability. We've had vague legal threats over the years and given the nature of some of the discussion we just don't want someone to end up in hot water for anything that happens on here.
