Yeah, okay. When you mention it like that, then it's understandable. The thing is that the ones I've heard talking about this (well, what I've read actually), they seem to truly belive that they'll earn a shit ton of money on each 5th post. Which basically means that they can create whatever crap they want, the 4 first ones, and then make a million bucks on the fifth, and that's not how it works.
Even if the odds are 80/20, that still means it's a numbers game. You can earn on five posts in a row and nothing on your next 25 ...
