Sounds like American workplace culture in a nutshell to me. If so, LinkedIn is actually doing it right.
The only utility I get out of it is that I can put up my resume and get recruiters to contact me. Which more than makes up for everything else since it has led to job offers
2 out of my last 4. There's a huge amount of spam. Mostly from big Indian firms looking for cheap labor to staff out a contract. But if you filter that out most of the other messages are legit that have a realistic potential of a job offer.
“Congratulations on hiding your misery for 10 years!!!”
The number of people willing to do that on LinkedIn is a bit shocking....
