is online publishing that relies on contextual advertising now a truly valid & sustainable business model?

Clear answer: Yes it is.

Explanation: Anything can be a valid sustainable if you have the right skill set, the right marketting, and enough funds to reach profitability.

If you build it they will come. If you build it really good many will come. If you build alot of them, even more will come.

So YES you can have a "truly valid & sustainable business model?" just using contextual advertising IF you can eat while you build it until it reaches a level that, even with market fluctuations, you can reach profitability.

BTW: Isn't this exactly what most of us are trying to achieve?
