The thing I find really interesting about this is not the trend (mobile up, desktop down. As Lehrer said, this we know from nothing!) but the patterns. Mobile clusters far more tightly than desktop does.

I'm not sure what this means (desktop users are weird? There's a lot of bot traffic we're not catching? That's my guess) but I thought it was pretty and might provoke some hypothesising. So, here you go!
