Firstly I think Steemit limits itself by mainly being a bloging posting platform. But over time I think many people will gravitate to steemit and develop little niche sites like already herein. Food or photography have solid audiences and sports seem to have a lot of followers.
No one can say the price of steem has fallen. Someone just overpriced it by eighteen hundred percent. Economics show the price of steem will fall to its law of supply and demand and that is now approaching something like stability nears its current price point.
Over time steemit will develop a following and grow into its own niche marketplaces. People will post either because they like to post or becasue they can earn some money. The main reason steemit is quieter now is most of the click baiters and bots have been dealt with.
Time will tell but steemit is worth having ; )
