Which people/handles should one follow on LinkedIn and Twitter to learn new

Give for both platforms. Serious question. Don't put Raj Shamani, Sharan Hegde as answers

My LinkedIn feed is filled with copywriters and ad agency people - so it is full day of jokes and lolling. No learning. My Twitter feed is either memes, news or hard core tech. No learning again.

At this point I'm learning new stuff over Instagram now 🥲
