A while back I was in the office at a Fortune 500 company. I was getting in the elevator to go home around 7:00 PM, which is later than I would've liked. A few other people boarded the elevator too, and we exchanged knowing nods and grumbled about late nights, the excessive workload, and bad weather.
The next floor, our CEO got on. Everyone's attitude shifted 180 degrees. We all had smiling, perky, and enthusiastic. I don't subscribe to the deification of our executives, but in that moment, I certainly acted like I did.
Anyway, on LinkedIn, people act like their current or next CEO is reading their posts. Because they might be.
I agree that it's fake, and I find my personal LinkedIn newsfeed to be extremely unpleasant - and more or less useless - to read. But when push comes to shove, the next time I'm around the CEO, I know I'll have the same fake enthusiasm.
