After you post something on LinkedIn, do you double back later to see who commented? Do you thank them for their thoughts by adding your comment to theirs?
Today it is largely electronic interaction, using keystroked words for your thoughts to be dispersed globally over the internet. You do not know who will see your comment, where they are, what they do, why they do it, and can only hope you have made a difference in that/those life/lives when they read your thoughts.
Worth the effort? I say yes.
If you see a colleague commenting, join in and make it a conversation. Raise your viewpoints, respectfully disagree and tell why, or pat them on the electronic back for an idea you had never recognized.
Add your why to theirs. It’s how we grow, how we adjust to new concepts, how we improve ourselves. We need each other’s input and no better place to place it than LinkedIn.
Please be conversant.
