There's something very, very weird about it. I live in Canada, where it has caught on in a very real way, and the people doing it genuinely seem to think it does something. I grew up in a managerial class, and so I've picked up on the art of recognizing when there's some ulterior motive; and here, I haven't picked up the faintest whiff of it.

I haven't been able to make any sense of it, but I'm confident that whatever it is is weirder than it seems to be; and it already seems pretty weird...
