In real life, you get one vote for each ballot measure, each office ... same as here, one vote per node, fair and democratic
Partially true. You get to have *at most one* vote per node. But I cannot vote on every node - I only get a limited number of votes per day. And some people get more; some people get less. That's not the case in real life (well, at least not for public offices). We've done away with the "number of votes scales with the amount of taxes you pay" quite some time ago.
I seldomly vote, and don't give a rats ass about XP. I don't care much at all about Perlmonks voting and XP system, just don't try to compare it to "real life". It doesn't compare.
