Further to that, my feed have been filled with Certification posts. Folks would boast about their 3 hour Certification courses with long cringe posts! And LinkedIn would not stop it, because they need to sell LinkedIn Learning!
I just feel like there should be somewhat of a boundary between personal and professional life. There are things I would say to my friends that I wouldn't tell anyone in charge of giving me money, at least not directly, and I feel like LinkedIn (purposefully or otherwise) is actively trying to erode that boundary. It's horrible.
But, yeah, I keep my LinkedIn--to the degree I use it at all--very anodyne except to the degree you have relatively extreme opinions on specific tech topics.
My political opinions are pretty normal (basically typical American lefty), and if my employer were to find a blog post I wrote about universal healthcare or something it's doubtful that they'd fire me. That's a little different than me plastering "BIDEN 2024!!!" all over my resume, and that's why I utterly hate LinkedIn.
