I'm surprised some people think that way because it is false by every account and incredibly short sighted. Content creation ultimately increase the value of steemit.com as a website and increase the potential reach through the search engine and social media.

Also, Steemit.com setup is a distribution mechanism to get cryptocurrency into as many hands as possible and therefore the best way to bootstrap a cryptocurrency market. How many people have been introduced to cryptocurrency via Steemit.com is staggering.

There is indeed some people from who are here to extract but those people don't get too far since their content usually sucks.

As for investors, they will be rewarded but that will happens through time by having a platform(or platforms) that are used by millions of people...not thousands.
