LinkedIn has become a place where lots of people share astrology beliefs because it offers the perfect scapegoat for workplace chaos - it's way more comforting to blame a cosmic phenomenon than to admit the project was badly planned or that someone messed up. I've seen people in my circle use it like a corporate meme, where nobody really believes it but everyone jokes around: "Oh, Mercury retrograde, of course today's meeting was a disaster." It's basically a laid-back way of dealing with work stress, mixed with a dose of irony and social media trends. The truth is there's no scientific correlation between a planet's position and a bug in your code or an email sent to the wrong person, but that's what makes it funny - it works as a shared joke among professionals who are burnt out and need to blow off steam.
