Now that I think about it, I only really cycle through three mmo's if I'm playing any- MapleStory, Survival Project, and Audition. I only go back to MS if I have a friend ready to play with me, but for SP, I'm always playing on my own. I don't know anyone irl/online who's heard of it. Audition's more of a guilty pleasure so I play that on my own as well.
My wife is the only person I know in RL who plays Entropia Universe with me.
At any given time though there are over 100 people online from my ingame friend list. (more aquiantances than friends)
Of those 100+ I would call 15-30 friends.
Of those 30 'friends' either me or my wife keep in daily contact with 20+ either through skype of phone or text.
