Well, you also have to put in to factor that the average \"age\" of Planeshift stays the same (14-16 would get the most out of it, I would guess) while the longer you stay the further away from that you get. I\'m not saying it\'s not fun when you\'re older, you just connect less with the people.
So really, you can theorize all you want as to the different mindsets of the \"new\" and \"old\" people (speaking in terms of how long they\'ve been a part of PS), but generally the older the new person is the more accepted they are.
