You may be familiar with Heywood Banks's song "Interstate 80 Iowa".
Someone with more skill than I at machinima should do a parody of this song, inspired by Chris Pirillo's BS characterization of Second Life. "Registration... welcome area... porn, porn, porn, porn, porn..." etc.
Then, fade to black, cue soft laid-back music, with voiceover: "But to know what Second Life is really like, don't listen to the bloviation of pundits who tried Second Life once a few years ago..." and fade into shots with voiceover descriptions of just a few of the amazing places in Second Life that have nothing to do with porn. (And trivially nothing to do with gambling, seeing as how that was banned from Second Life three years ago.) Finally, "Second Life is what you make of it. The only way to know what it's like is to experience it." Show URL, hold, fade to black, roll credits with music.
I haven't had much luck with past machinima requests, but I think this is an important one. Anyone?
