Linkedin has large elements of a social media platform. I was advised that liking and commenting on others folks posts would elevate my own profile, and I should also write papers and contribute original content.
They were right. Consider this graph. A few weeks ago, I started actively liking and commenting. Last week, I posted about Tom Brady and analytics.
Those searches include recruiters who are suddenly picking up the phone and calling. This is a real world outcome. You would think a recruiter would just want to see the most qualified candidate, but the platform biases them towards candidates who do stuff on Linkedin. Weird!
