Then you have market fatigue for the user. After living in a world of Twitter where you can consume all the things you desire and discuss all those things in the same setting, very few people want to be jumping from app-to-app, website-to-website to talk to different groups of people about different topics.

Twitter was (still is?) a true community center, digestible in a format that's quick and easy. That's the allure to the average user.

There is also the discovery component.

The Athletic (https://theathletic.com), which is an excellent source of news for all sports leagues, does have a pretty decent place for discussion, but its engagement pales in comparison to the likes of Twitter (and even Threads now).
