Alexander Kustov on LinkedIn as the Switzerland of the Internet:

LinkedIn’s format (longer posts, real names tied to real careers, a less snarky default register) does a lot of the work of civilizing discourse without needing heavy moderation, because when the poster is visibly accountable to an employer and a professional reputation, the median comment tone shifts correspondingly, and bad-faith quote-dunking becomes rarer. There are also no anonymous accounts and almost no sub-tweeting; the median post reads more like a memo than a hot take.

People can still disagree or criticize you heavily if you post something provocative, but they are much less likely to do it in a mindless or righteous way. In some ways, LinkedIn feels like an academic conference: people are civil, sometimes too nice, and not always willing to criticize a colleague openly. That conference-style politeness can smooth over real disagreement, but it is a much better failure mode than ad hominems and pile-ons.

This is also my observation, along with what I wrote in 2022.
