Thats nice, i have enough of all the spying around, usually publishers (google) forces you to watch content you don't want to, even in gmail now, if you purshase something your gmail account you will be spammed with google ads, and you will have to see annoying content who have nothing to do with you, i have this problem with google searches also, as 'they' show me what they want me to see.
The idea of displaying only the content i want to see is really interesting as long as there is no fancy algo who will manage this automatically as automation in this domain is far from bein matured, just look at google.
