Thinking more people are going to engage with you on mainstream social media “because everyone’s there” is like thinking people at a stadium concert are there to listen to you. It‘s only true if you’re one of the ones on stage. Not so much when you’re huddled in the nosebleeds.
Forget the numbers. Forget about “going viral” (leave it to the psychopaths in Silicon Valley to make virus-like behaviour aspirational). Embrace the joy of interacting with one another on a human scale.
