I don't like this idea. I have already moved a lot higher in the ranks than my PERL knowledge alone would allow, simply by voting for nodes I like. Making it easier to gain points will make it much harder to tell the learned with little time to vote from the learners (like me) with a lot of time to vote.
I dunno, I feel like I've learned a lot just from reading other posts... I don't really care if I get XP or anything for it... my learning will come back in my answers and in my code.
