Oppo-pinion: Nitrogen in tires a bunch of BS?S

so I have numerous friends, none of whom are gearheads or know a damn thing about cars, showing up with green valve stem caps lately. I actually bought one with green caps. One of my buddies actually has a leak and was bitching about how much it costs him to get it filled every week (vs fixing his corroded Volvo rim, typical). I have always advised people I know that with the older cars they are driving, this is not making a bit of difference. Anyone else here have the N bug, or have we decided it is crap?
