Does 'FREE' really comes free in internet?

Tweet

From the last one year I have been searching for ways to earn some extra income from the internet.But most programs like paid to read, paid to surf, etc. that I know so far are only a waste of time. Being frustrated, I tried to launch my own website through which I thought of getting extra income.As I have no money I search for the place where I could find one for completely FREE.By chance I have found one, but Trying to get something 'FREE' have 'cost' me a lot of time. Does anyone encountered this kind of situation?
