No it actually doesn't matter. People get too concerned over titles/levels and XP. It is the same all over. A game site I am on, people rush to get the highest level and get rather violent if posts get deleted, or they loose levels. As I have said there and vroom has said here "A million XPs and a cup of coffee gets you a cup of coffee"
What I am calling is the voting for the xp is when you see a post that basically says "Yea you're right" and it has 10 votes. Heck, Merlyn can make a strange post and he would probably get 15 points for it.
My only gripe about the XP whoring is the fact they rush to get bad posts(ie --'d heavily) removed. Sometimes these posts can actually teach things.
