Meh, I prefer something I can operate/monitor. The guy who runs that is very secretive about all of his setup, to "prevent abuse" (unclear what sort of abuse he's afraid of), but highly opposed to others building their own.

Fair enough, I didn't necessarily mean that server. It's true that he's secretive about his setup, but I wouldn't say he's highly opposed to others, after all he's the mod of the subreddit and yet people can freely discuss how to setup their own.
