I have two points on this:
First, XP should certainly be awarded for writing a useful tutorial. For example, Programming Perl.
Second, given what I have seen so far as moderation goes on Slashdot, these people if they contributed here will probably be positively awarded to such a degree their xp will rise quickly anyway
RE: Should Perl Gurus (Wall,Schwartz,Christiansen et al) receive mega XP based on who they are?
