Think of your favorite social media platform as a place you go in real life. Maybe it’s a coffee shop, church, a park. Somewhere you go to spend time with people face to face.
Now, before you post anything online think about this, if you were at that favorite spot, surrounded by people, some you know and some who are strangers, would you say out loud what you were about to post online?
If what you were about to publish was about someone else, if they were in the same place, within earshot, would you say what you were about to post? (Would you say it to there face?)
If the answer is no, you probably shouldn’t post whatever it is you are thinking about posting.
Sidebar: Posting a selfie is like being in that favorite place surrounded my people and yelling out at the top of your lungs, “Hey everybody, look at me!!! Look what I’m doing! Aren’t I amazing!” (No one wants to be that guy.)
