Do these work like Kool-Aid points? Can I get a mail-order cassette tape or plastic pitcher if I mail in 100 points?
Dude, if that's the case rep me now!  Those Kool-Aid pitchers were the sh*t!  Whatever happened to Kool-Aid man?  Did he finally get too elderly to break through walls all the time?
Kidding aside though, if you guys want to make this rep thing useful then might I suggest linking it to the post and not next to someone's sig.  That's how it's done in other forums and it works a bit better as you actually have to read something the person has typed and can only "like/rep/whatever" once to that post, so no doubles.  
That being said that doesn't work very well either.  I think my like count is around 1000 over at psx scene, which makes me feel good, but seems a bit much.
