BeReal is all about "today" and doesn't even let you see the past.

Old Twitter was all about the newest-at-the-top feed

X still is about what's trending and showing you recent things it thinks you'll like.

Sure, FB and Instagram show you "memories" of today in the past, but the core is still recent content (and 24 hour content on stories).

Even blogs are all about what's the most recent.

Are there any social platforms that are about evergreen content?
