I used to run an ISP, everyone thought that the internet connection was totally free and I was basically being a greedy capitalist pig.
At the time I was paying $400/mo rental for a 128kbps link (just the link) and then 19c per meg downloaded (that's right, $190 per GIG). Free, my ass!!! I ended up closing the business with debts of several thousand dollars which were conveniently paid off by my discovery of adult affiliate programs. :D
