Last year, I opened an account on Facebook hoping that I could find a way to make money with that. (I did also for Second Chance). We can build application and make them viral. But I have found some ideas of apps. Probably the ideas I had can become popular, but how it's possible to make a lot of money ? We can put ads, but I am not convinced that it produce a lot of money... I want to know if you have made some Facebook application and how do you proceed to get some great revenu ???
