You have to have a massive website like digg or myspace, those website bring in millions of visitors on a daily basis and they make a ton of money selling ads.
I read facebook case study for business students, it makes less money then it spends on servers. The dude is paid by investors hoping to get their cash back.
If a new idea, which really clicks huge on Internet result in Million Dollar earnings. May that day come to ME & U!!
omg! I made only 999999 can someone donate $1 ? Well, you can't make it from a single site unless you have digg, plentyoffish, etc. combined into one.
