i love stories like that nanook because they illustrate how file sharing is becoming so everyday & so mundane, so integrated into ones' normal lifestyle and such a habit. but i hate the cavalier attitude about leeching, not least of which because if isp and campus capping polices are going to change there has to first be a user who cares about them.
but i think maybe there are an awful lot of people running around who think like your coworker does.
we were all newbies once and maybe we didn't think it through at first but we came around - and then some. i know i've chnged peoples' minds about this, i'm sure you have too.
