Same. I stopped when I realised it was passively teaching me celebrity gossip, which I never wanted to know.
It's so easy to absorb 'celebrity' gossip, I always wondered if it'd be possible to do the same with say science or maths, if it was presented in the same kind of format.
Easy way to find out. Remove the pictures from celebrity gossip posts, and see how much you remember.
I think the hardest part is the rigour. Math and science build on concepts over time, and mastery is easier with more hands-on experience. Just presenting it to someone in a feed might be waaay too passive for absorption.
Somehow I’d always end up doing this most right in the middle of finals.
