Hm... what we lack might be a kind of recommendation feature, so that the curators who do actual curating ( as opposed to a bot upvoting everything by X 2 seconds after it's posted) can get together in groups and vote amongst themselves to create weekly Best Posts in all the different categories.
I could imagine having a kind of newsletter like that...
Another option could be a recommendation feature so you can selectively allow some people you are following to recommend posts to read. like sharing on a friend's FB wall works nowadays.
There's a lot of features yet to be implemented or thought up, Steemit still has some growing pains to go through.
I suppose the resteem option covers most of that, although I'd sure like to know who resteemed my posts - there's a lot of development yet ahead of the team, yes.
