I don’t know what the point of a subreddit would be. Reddit is more like a news feed and it is impossible to keep a conversation going for a longer period of time. Not to mention that reddit was never intended for long conversations.
And other than that we don’t have nearly enough content to keep the subreddit alive. Here in the forum we can talk about everything and anything and in addition to that have a homepage to highlight important posts, news and speedruns in the huge banned and show them off nicely. Not to mention that the admins have full control over the website and can change some stuff, like the landing page that was created for EP2DQ.
So yeah, I see no point in a subreddit.
