I too would like the answer to this question but can't really trust Steemit to answer this question truthfully (and therefor negatively affects the quality of the answer). What I have read and what I have seen posted on Steemit in practice seems to indicate that Steemit is a positive news generator when it comes to talking about itself.

This is the result of incentives that reward people for generating content that increase the value of a Token. (in this case Steem) So i'm not going to give you a yes or a no answer. I will say this instead.

Steem isn't an investment. It's a receipt for purchasing good content on Steemit. If it is viewed differently then Steemit will only generate content for pumping Steem.
