There are so many comments from people who report being inundated on LinkedIn by recruiters. I don't have a LinkedIn account, and I _never_ hear from recruiters. My name is out there; I'm on other developer-centric social networks and generally have no compunction about giving out my email address and phone number, and I literally don't have this problem. I have over a decade of experience in many different software engineering roles, so I assume I would be a plum prize for unscrupulous recruiters. (I used to receive messages like these, but they dropped off around 2013. I assume this is roughly the point that recruiters realized that they could focus on LinkedIn to maximize their conversion.)

So, serious question: why do you have a LinkedIn account? I know there is theoretical benefit in maintaining connections to professional acquaintances, but in sticking to email and a few alumni Slack channels, I have never felt limited in that department. What is the benefit of your LinkedIn account and why do you keep it?
