People have been leaving ever since I first signed up for the game. So it would be possible to argue that my arrival is why people are leaving. (Perpete might like that one.) I disagree however. I think there are many reasons people leave. I don't claim mergers will stop people leaving. I'm not convinced anything will.
I think there were one or two users who left for other reasons, so you're off the hook. ;)
(Actually, I just wanted to point out my personal appreciation that you're not falling into the fallacy of assuming that X feature/bug/situation that you're displeased with is the cause of people leaving. I of course expect sound reasoning from you, so I shouldn't be surprised, but it's still nice enough that it actually spurred me to post.)
