I looked for "happiness" in Internet, well, I did'nt spend much time, sincerely, because I did what is more simple: write happiness in Google searcher. But it is enough to see that what happiness is for Internet is, in one hand, a subject to define (in wikipedia or in the catholic encyclopedia, for instance) and on the other hand, a selfhelp topic for excellence.
There are more than 53.000.000 results from "happiness", by the way.
