I read a quote once that went something like (paraphrased): every organizational app has to compete with email and every form of social media has to compete with group texts. And I think that's accurate.

If you pick random people they'll have often very old group texts. Family, friend groups, etc. These are used to organize, disseminate news and so on. 10+ years ago, a lot of people did these things on FAcebook. Group texts work on all platforms. They don't have ads. They're chronological.

From an engagement perspective, algorithmic recommendations and ranking (ie the newsfeed) has "succeeded" but it killed the use cases that people now use group texts for. And I think the two are fundamentally incompatible.
