I agree with the problem.
But I think popularity is kind of like capitalism: you can't avoid it, and if you pretend to ignore it, bad things happen.
If social media is not just going to be a morass of random unsorted clutter, how else can you rank anything except, ultimately, by something that boils down to what people want to see?
So what do we reform it to? If we can think of something that people want to see more, we don't need to cry for social media reform--people will just do it when it becomes available. And if we can't think of anything, aren't they just going to get essentially the same thing we have now, because people want it?
