The strategy is writing as much articles as possible so you get billions of visitors per month from long-tail traffic.
One thing I can see happening is huge amounts of people getting into it because it's easy. Anyone can do it. Google can't tell the difference between a good post and one from a great writer, so people who have a lot of experience writing are going to be most at risk with this technique...
Reason being you're basically competing with everyone around the world with a basic command of the English language.
Imagine if 10 posts per day got you $10K per month. Teams of people from cheap countries could hook up and write 2 articles per day on a few sites, then split all the money.
The entrepreneur from a more expensive country and on his own will be screwed.
I think it's the same with everything: the tactic is great until it's let out of the bag.
Isn't it better to choose something you are good at and become a master at it? Then you're competing with a lot less people are have more chance to be successful?
