Online applications and life

Hi, I was very interested in the question here. There is a huge crowd of people creating web applications. After the beta is released, reviews are written about it, it flashes a week later on another in blogs, after which, as a rule, everything calms down.
Actually a question. They generally someone uses?
There are two most common answers: no in Russia, because even so you can get a normal application with a crack, in the rest of the civilized world, yes, because piracy is punished.
I would like to hear your point of view on their viability, better with life examples.
