Yes, it's very likely that I know different folks. That's why I hedged my comment by noting that it was purely anecdotal: I tend to associate with computer scientists, mathematicians and medievalists. The first and last groups tend to be most interested in homogeneity, in my experience.

Besides, if we're to say that IE is "back in the game" then surely we should count only those who make a conscious decision to use IE; otherwise we're using vastly different terms.
