I like LinkedIn. I would like it better if people on the platform were more engaged with either the content they post or what they are reading and enjoying. I recently had a professional "viewer" that frequently viewed my profile ask me why I asked him to connect. This puzzles me. If you are interested enough to return to my profile, let's have a more formal introduction. Can I help you with something? Do you have a question? We share connections, professional interests, and you keep lurking on my profile pages. What is the mystery?
I manage a linkedin group, Continuing Medical Education (CME):The Collaborative Think Tank where there are close to 1000 members that do absolutely nothing. I know they consume information because I hear from many of them privately but with the exception of generic posts that advertise a vanity project or an event posting--nothing. There are other groups that I visit where good luck getting anything posted if you aren't perfectly aligned with the views and opinions of the manager of the group. Or groups where your comments have to be moderated. The lag time for responding to comments on your own posts can take days.
Many of us are still learning the platform. We will do better when we know better. Here is a great resource for many of your questions and many more you didn't even know you had. Have you noticed that many of the listicles just recycle the obvious? Upload a profile picture? Duh. Why don't they just add "breathe in" and "breathe out"
There is a group called The Missing Link that encourages open discourse about the platform and how to optimize your profile and interactions. If you subscribe to the podcast you are invited by text to join a private group. I suggest you visit and see if you care to join. We shouldn't overlook LinkedIn as a unique engagement tool as a source of digital networking and message dissemination. The wheel doesn't have to be squeaky to warrant attention. Sometimes we just need to be open to being "along for the ride"...
