Yes, I realize that. I've even started a few (report the spammers and postrock). You can't unsubscribe from the culture. If programming or minecraft end up filled with memes and crap, you're out of luck unless you can get enough momentum for a similar new subreddit.
I've found /r/soccer is pretty low on the "internet culture" stuff. And /r/gamedev, while too small to sustain much interesting discussion, does provide good links.
But yes, any large subreddit on any topic is infected with all the rage comic and meme garbage that Reddit inexplicably loves. You have to figure that the average age must be around 18-20, which becomes very tiresome if you're more than a few years older than that.
