The point of reputation is mainly to show that you contribute to the community. Once you're able to post URL links there's not much else that it is used for. I think it'd actually be better if there was less ways to earn reputation, such as if you only get it for years active on the forums (50% of the year you sign in?) and if you post the answer to someone's question or a tutorial or game to the arcade.
I think you need 5000 to edit tutorials too, but as Naji is already at 8000, I think10000 is not useful feature wise.
Agreed with the user given rep for non feature based rep
