But that's just social media in general. Doesn't mean it can't be valuable.

> Twitter didn't really grow from being a solution to anything - it grew from being unique at the dawn of social media. So it is kind of its own thing.

This doesn't mean that something better can't be made. Lots of people clearly don't want to support X anymore, whether for political reasons or for UX reasons. I don't see why "a better Twitter" is somehow not possible because it wouldn't "solve a problem". Why can't the "problem" be that X sucks ass but there isn't a good alternative?
