Does anyone think the world is better with this in it?

The nice thing about LinkedIn posts is that it’s clear that everything is an ad. Reddit, Facebook, etc started with people just posting to communicate and socialize, then were (mostly) taken over by ads / influencers pretending. With LinkedIn there’s no pretense and no wheat to sift from the chaff.

It’s just marketers marketing to each other. If that’s useful you can join a mutual promotion group and auto-comment on each others’ posts without damaging anything of value. If not you can stay away and completely ignore any posts when you come back for an occasional job search.
