My entire post was questioning that "common sense" that to me was never common. Maybe I'm retarded or blind but I would appreciate some pointers about how "discovery" happens in these other social platforms.

My experience on Twitter was always that I would find people by seeing them engaging with other people I had been following already.

And there was a sidebar with annoying endless suggestions of people to follow that would only show people who were already very famous with thousands of followers and whom I already knew and had already decided to not follow. What else do they do?
