What we got was Myspace and its friends. The technology delivered. But once everybody could broadcast, nobody could be heard.
So we got Facebook, which started out as "me, Me, ME" and ended as a broadcast medium with targeted ads.
The best we can do so far is to have lots of small communities, as with Reddit. Or just passively doomscroll the infoblasts.
Where do you get the "nobody could be heard" from? There was the rise of Myspace celebs, which I suppose could be a kind of early influencer. This had an influence on the direction that certain popular arts, like comedy and music went.
