I agree with you about having some kind of browser or control center. Vastly improving post visibility is pretty much essential for Steemit and likely every other platform currently or to be built on the Steem blockchain if there is a desire to gain and retain users, and thus grow. Organizing the content is definitely a part of improving visibility. Communities would be another if it actually gets implemented. Having millions coming aboard and then dropping off would not be good. There needs to be a place for people to go and find their niche.
