If by "Bloggers" was meant those people posting in Steemit, whatever their periodicity, then, yes. Steemit without bloggers would be nothing, as nobody will be posting.

I think that there is no a correlation between Steem value and Steemit success as a platform.

Here we are, posting, whatever the price of Steem is.

It is understandable, also, that "investors" -speculators, in fact- dislike the fact that Steem/SBD are the coins of the Steemit platform. That's because most people is going to exchange their SBD to any other cryptocurrency. That makes the Steem/SBD price tending to lower and lower. That is what happens when most people are selling its assets.

But I believe that the ones who should adapt are the investors and not the platform.
