I'm a middle-aged person who is not up on the latest trends and am not a social media user. But a few days ago on CNN, the anchors were going on about the latest celebrity "selfie" that had "gone viral." My first thought, of course, was "why in the #%%^ is this news?" but then I looked at the photo they were showing. One could see that the subject was not holding a phone or camera, and the photo was clearly taken at a distance of 20 or so feet. In other words, it was not taken by the subject. Shouldn't that have made it a "someone-elsie?" Or better yet, a plain old-fashion "photograph?"
On the other hand, the celeb had posted the pic to his own something-or-other (maybe insta-gram) account. So is that what made it a selfie?
