Advertisement is a form of monetization. Now the question is about what you mean with "viable economically". Operating a website is pretty cheap and many non-profits are happy to do it for you for free, for a free-price, or for a membership due (usually 5-20€/year). If you're trying to get an income from operating a website (or any other creative activity for that matter) that's a different matter. That's what i was referring to with "monetization". I personally believe that we as a species would be better off if less energy was spent trying to monetize everything and more into providing actual services to actual people.
