TL;DR – I only use LinkedIn connections for people who I could personally introduce and recommend.
I realize that many people use LinkedIn as a tool to grow their professional networks, meet new people, “bookmark” attendees they met at conferences, or build as many connections as possible. And that is fine. It just does not work for me.
A core functionality of LinkedIn is the ability to see and introduce people who are two or three degrees away. All my connections are visible to people several degrees away as someone they could get an introduction to. So, to me, it only makes sense to connect to people I feel confident personally and professionally recommending to someone else.
I am more than happy when anyone reaches out to me through LinkedIn because I do love to meet new people, deepen relationships with acquaintances, and help folks out however I can. I am simply asking that we do those things through other channels.
