I would assume it would only feel empty if you actually cared what the other people think. Let's face it, if you and your 30 clan buddies join the game and take over a realm, do you really think they care what the other players think? If they don't take part in any of the rest of the community, would they even know what the other players think?
They obviously don't care what the community thinks, because they don't take part in it. They only care what their clan buddies think.
The prior posts were referring to one person with multiple accounts. Playing on your "own" tends to pale in a social game like BM after a while I'm sure.
