Am I the only person who keeps thinking of Rep as XP? I keep thinking (and almost typing) thinks like:
"You should post that comment as an answer then you can earn some XP from it." or "Man I have earned a lot of XP from that question"
I almost think we could rename Rep on RPG.SE to XP. But of course we shouldn't because keeping consistency with other StackExchange sites. (Note: I am not suggesting we should rename Rep to XP. Just pointing out the interesting parallels)
