According to Oxford Dictionaries, oversharing means to “reveal an inappropriate amount of detail about one’s personal life.”
In describing several oversharing incidents by his students, Stephen Winzenburg, professor of communication at Grand View University in Des Moines, wrote in The Chronicle of Higher Education that “Often the less the students know the person they are communicating with the more willing they are to spill. And they do it bluntly, now that they are used to summarizing life in 140 characters.” But it’s fairly obvious that it’s not just students or millennials who overshare, there are plenty of examples by people of all age groups, professional backgrounds, ethnicities – basically people from all walks of life.
Before you post online, think about whether it’s best to share these things with the world, or perhaps better to just keep them to yourself. After all, “anonymity is a hard thing to replace.”
