I get a bit annoyed every time I log in and see Fubar wanting to co-opt my social networking status to advertise this site, for the pittance of 50,000 fubucks. Given that they offer a $7.50 1-day blast for 10 million:
750/10000000 = .000075 cents per fubuck * 50000 = 3.75 cents for your giving them access to twitter or facebook or 7.5 cents for both!
Or did I do this all wrong because I just saw someone in my bartab "liked" fubar on facebook for 1.875 cents?
Anyway... you may all extrapolate from there
