I took a long break (maybe 5 years or so) but I have recently started using both FB and Instagram and have been surprised at how positive my time has been on these platforms. On FB I have been finding interesting local groups and events (just moved to a new city) and on Instagram, I have been enjoying seeing updates from real friends.
On the other hand I recently deleted Twitter from my phone. I love twitter for getting interesting infromation and staying up to date with news, but the whole culture there has just turned into cheap dunking on one another, and its just guaranteed to leave you feeling angry about something. Extremely disruptive to mental state.
I spend some time on the TikTok-like products as well (youtube shorts / fb reels) and have found them to be just a really easy way to completely waste an hour for no reason whatsoever. Less disruptive to mental state than twitter though.
Would be interesting to write an algo to generate defensive puzzles, seems like you could look at positions where the delta between the best move and the next best move is very high in terms of centipawn loss.
