Tech/programming stuff is exactly why I did nuke mine. Going isn't as meaningful if you leave a bunch of value behind when you do. While I'm here for entertainment now, I'm often spending my reddit time during work hours on vendor-hosted support forums, stackexchange, etc. now.
Gradually, that library will be relocated to other places. Instead of just not going, I think it's better to take away others' reasons for going too, give them reason to seek out better libraries.
Curious. I'm reasonably sure the option should be either in the settings right where you took that screen shot or under the subscriptions section in the Google Play app store.
