This one is on its way to becoming part of the social media ecosystem. That's what the "Updates" feature is.

To get an idea of what it will look like, check out Instagram users who use it for both 1:1 messaging and social media (1:many) features. Which (again anecdotally) is widely used in younger generations.

Few of my friends use Instagram or TikTok, but I think we're just outliers. I see many (young) users, all the time, whenever I'm on the train.
