This post is more a rant—similar to the bikes on sidewalks screed—than my usual post. You are warned.

Cases in point: Two to three weeks after ending relationships, two people posted self-portraits with new love interests. In one case, the poster was still linked as a "friend" with the ex; in the other case, the two people had so many mutual friends that, although they had "unfriended" each other, photos and comments on photos readily popped up in the ex's newsfeed.

No—the posters weren't trying to wound the exes. They had ended the relationships; the exes still waded through the muck of heartbreak. Instead, so caught up in bliss and compelled to publicly record it, these perfectly kind, generous people forgot that what they posted would hurt someone else.

Profound, isn't it?

People believe that if something isn't on Facebook, it isn't real. Yet by taking time to record moments on-line, people miss part of the real-life experience. And their compulsion to legitimize events on-line trumps their empathy for others.

In these ways, Facebook fanatics cheat themselves out of real-life connections: interpersonal relationships and fully experienced, shared moments.

Practice some self-control, folks.

Document milestones, sure. On Facebook, I post highlights albums of vacations. If I've got something big to announce, have information that might be useful to people, or need help with or perspective on something, I'll post on Facebook. I link to blog posts there, too.

But I don't record every movie I see, every lunch I have, and every amusing thing my dog does. (I use Twitter in an entirely different fashion, yet I don't log my every move there, either.)

Why should I? What value is there in that for anyone? And what possible harm?
