"It's almost like capturing a photo of yourself with that person," said Chris Abraham, senior vice president at Social Ally, a social media firm. "For a second there, you've breached their celebrity. They've actually allowed you to come over and take a camera shot of you two together, and you can share it with all your friends."
I don't think all of us are as detached from reality as that guy. You can't replace experience with a hashtag. Imagine an adult saying, "I remember that retweet like it was yesterday." Won't happen. But meeting a player and getting an autograph or a photo? That's a memory people tend to keep.
