"Downvotes roll in"? At least not from my side. :)
Everybody can write about whatever he likes, and - of course - also about STEEM.
It's just my personal opinion (which nobody has to share) that it would be helpful for the success of the platform if whales supported more non-STEEM content and especially tried to spread their upvotes on as many as possible different kind of posts and users.
That means, if at all, I 'blame' the 'curators', but not the ones writing about STEEM all the time.
