I think LinkedIn suffers from people treating it as an extension of a CV or prospectus, which probably isn't an unfair assumption on their part. Which means not introspecting failures, only commenting or reacting on banal platitudes, and not saying anything that might be remotely controversial for an employer.

This is sad, but as someone who will happily admit failures, frustrations and annoyances on LinkedIn I have been in interviews where people have dinged me heavily for it. So far these have all been quite toxic work environments - maybe you could count it as a useful filter, but I understand given this why people feel pressure to do little more than copy/paste the same Oleg posts ad infinitum.
