The trouble in my opinion comes when these social networks begin to promote content to the user algorithmically. My Twitter feed is filled with content from users I do not follow. It makes up the majority of my feed. Likely, even if it was content that I was following, the most "engaging", or oftentimes "enraging" content, would be the content shown first.

If social networks were largely just content crafted by the people I follow, it would then be more representative towards a digital representation of the in-person social structures that would or do exist.

They make much less money that way though. Your average user would probably also use it less.

Even harder: Who gets to decide who gets the megaphone? I see the problems with "nobody, therefore everybody gets the megaphone", but I see nobody that I actually trust to decide who gets it...

i mean, in the literal sense most people don't get megaphones, so nobody seems fair to me
