It just makes it less likely that these normal people will be able to see the other normal posts from other normal people. Early Facebook's Wall was like that, mostly just friends chatting with each other about cats and babies, but then the company purposely started to optimize the timeline for controversy instead and it all went downhill.

It's not that there aren't normal people on there, it's that organic feel-good posts have a harder time gaining traction vs the sea of flamebait and sponsored ads and astroturfed spam. The signal to noise ratio was very, very low by the time I left. I don't know how it is these days...
