Hopefully the ball keeps rolling and more people jump on board.
Their is still a place for the posts that take time - your early series of "faces of Jamaica" were some of the most interesting posts I have read on STEEM. And those long form posts should definitely be highly rewarded and the ones filling trending. But yes, quick content and engagement will keep people coming back and form more of a social network and less of a dry content only network without much interaction.
Trending for the best posts - but a lively "latest posts and newsfeed" section.
