The problem with Facebook likes is they are so, well, virtual. I mean, you may get a bit of rush, and a little release of dopamine when someone likes you, but now the innovators at MIT have come up with a way to make it much more of a physical connection, literally letting a Facebook like hug you. Boston Magazine calls the new "Like-A-Hug" wearable social media vest new form of "tangible media." Which makes me wonder, what was wrong with the old versions, you know, actually hugging someone?
