Are you following people who are pushing politics on their LinkedIns?
I've found following relevant VCs, PMs, Academics, and corporate leadership has drastically improved my LinkedIn with almost zero noise.
Mute and unfollow people who post too much politics on LinkedIn, and engage with content that is more relevant to you. The algorithm will tune itself for you accordingly
If your network is filled with people who liked stunting on LinkedIn or doing unnecessary arguments it will come up on your feed.
The assumption is you will keep your LinkedIn trimmed and managed with only people you care about.
Make your LinkedIn curate better content by following people who generate actually insightful content.
Also, I am connects with actual politicians and staffers on LinkedIn because of my previous career and they almost never post any political flamewars on there. It's basically used as a constructive Twitter for those of us who don't need the noise that comes from Twitter.
I find it annoying that I can’t tell LinkedIn to show me less of this, like I can with other social networks.
Like content you find relevant and X out the content you find useless. In 1 week your LinkedIn will be completely tuned
Also, as someone who I think might be a 2nd or 3rd degree connect of yours, the Bay Area Asian American HS network has been fairly high quality. Leverage and optimize for the network of friends and alums who ended up becoming IBs, PEs, Engineers who deliver, VCs, Academics, etc. And then optimize to follow whoever they follow in turn.
