I agree. If you look at Steem Engine a lot of people have come on board to support those new projects and to do so they buy Steem. The new communities help people limit their feeds to stuff they want to read and these sub-ecosystems help Steem by creating a reason for new people to buy Steem. This brings fiat into the platform and the pursuit of the power that stake brings promotes hodling, so these two forces should increase the value of Steem.
