I suspect that just one update, among the many that we just saw, was related to mobile.
The difference? Pages that don't display well or fast enough on a mobile device don't show up. Mobile sites also need to work well on messed up public wi-fi and the like. I long knew that these limitations might happen on a pure mobile device search, but now I begin to suspect it's also affecting traditional desktop search.
It's just a theory of mine - based on very limited data. So I when I saw that post from @fabulousyarn I thought I'd chime in too and see if anyone else had something to say on it.
