Addressing the thread topic not the OP, I don't know if this qualifies as "weird etiquette", but when I first got an account, I thought that it might be awkward to go to rooms of people I knew from here - specifically that someone who knows me from ACF might be uncomfortable with me visiting her room on MFC. Turned out that it's not a problem, I'm happy to say. At least in my experience so far, anyway.
