I object to the idea that posting photos of cute kids is not beneficial to American society!

Everybody is always going on about how people waste time on social media, but I keep thinking that they could be doing things so very much less benign.

Anyway, this is a fascinating, if somewhat sinister, development. I don't know anything about Mark Zuckerberg's politics, but the ability won't be confined to him for long, if it even is now.
