I think that one of the best things for steem is versatility and shapelessness... As Bruce Lee said:

Be water my friend, be water.

Youtubers can be youtubers/dtubers here
twitter people can be twitter people
bloggers can be bloggers even use steempress
instagram - well we have lots of people doing exactly these one photo posts.

Now, the thing we are missing is communication and interaction between different levels of users (you know minnows, orcas, dolphins, whales - Kudos for exceptions and curation groups).

Also... steem needs consumerism, here everyone wants to be creator, but there is no need for most of the content out there - yes, we are young and in development but these are some problems that we face.

Have no idea what that was about, but like it matters. :)
Cheers
