I think the biggest problem is the need for a stamp, because who would think to even bring them? And who even knows what it costs to send a postcard. They're just beautifully stunning, stunning visual records of a trip. You have to sit there and think, how do i sum experience up for somebody? An o facebook, one line on facebook with a picture, just ever so much easier. It's sob postscards are so personal. For somebody to get something in the mail these days is so exceptionally wonderful.
