BecomeMe

I have no idea, but it kind of sounds like algorithms that attempt to show people what's popular with other people are being eclipsed more and more with algorithms designed to steer people's consumption in some particular direction (to create revenue, or to better hook people into a dopamine loop so they keep blindly poking at their phone). The organic development that happened when a big chunk of people in the world all decided that something was interesting or important doesn't happen anymore because the algorithms don't care what people find interesting or important.

Or, it could just be that more and more of the genuine humans on the internet are abandoning the "everyone has an account" places like Facebook as they become cesspools, and there's no agreed-upon replacement.
