Facebook comments are a fireworks show of impulsiveness, like much else with Facebook. Mercifully, FB just gave us the ability to edit things we wish we might have said differently. But now, our screwup is open for everyone to see.
Usually we applaud transparency at Gizmodo, but isn't the entire point of an edit feature to clean your tracks, whitewash the past, and leave behind a better statement than the one you cranked out to begin with? Not anymore. Whenever a friend (or foe) edits any Facebook comment, an Edited button will be tacked on -- click that, and you've got a big gaping window that shows the entire history of the comment. Every. Single. Change. Did you screw up a fact? Say something insulting? Hurt someone's feelings? Lie? It'll be there.
Of course, you can just delete any incriminating comment, but then we're just back to square one. Online editing is only good if it allows you to banish your inferior self expression to an unreachable internet vortex. Now we're all just going to make fools of ourselves.
