I really enjoy the Garbage Day email newsletter. (disclaimer, I am a paid subscriber.)

Distills the cesspool of the algorithmic feeds to present up-to-date trends, popular memes, etc. as well as a general commentary of the sad state of the modern Internet and our engagement-driven AI-training future.

I don't have a desire to join all the 'socials' myself, but it is nice to try and view at arm's length what 'the new generation' is seeing and thinks is popular.
