Like is not the ultimate evaluation of usefulness.
Many of my most useful lessons learned the hard way got poor metrics. Few engagements -> fewer views.
Thing is, if you tell the truth and people are uncomfortable with that, you won’t be popular.
People need to either
Option 3. is the way to go. And Linkedin, unfortunately, favours engagements, so, don’t take heed to likes if your content is good.
Algorithms at some point will always mirror the truth, don’t optimise for algorithms.
