No response. That's the default response. When you send an email. When you make a post on Facebook, Twitter, LinkedIn, or any other social network. We have come to expect this default response. Everyone's too busy, too many people are posting. There's not enough time to give everyone attention.
What's interesting is that the phenomenon also affects our in person interactions. I teach both online and in person and see the default response in class all too often. No response. No questions. No interest.
What would happen if you did something different? What would happen if you responded? Would that make you memorable? Remarkable? Perhaps. Give it a try.
