I believe of working our way up with proper network (getting to know good steemians here) and little by little investment is good. Not everyone has the money they can invest and be ready to lose it; because all investments have risks, and not everyone can afford to lose the scrapes they have just yet.
Interesting article though. This actually explains why my votes are still pretty weak. I guess I might need to really pick and choose the best 12 posts I like over the day, maybe resteem them first and spread out the voting throughout the day to get a steady return of voting power, and also able to contribute (with curator rewards returned later)
