I'm on it...
Would not call it adult at all...
Here's what you get:
1. self promotion and a lot of arrogant people that « know everything » and try to monetize themselves
2. corporate greenwashing
3. very dull conversations where nobody takes a stand cuz that might be bad for self promotion (see point 1)
definitely not enough #GIFs (I probably posted 50% of all the GIFs on LinkedIn on my own)
