I always board last. I'm going to be spending too many hours on the plane anyway, why would I want to spend yet another hour sitting motionless on the tarmac when I could be out where there's power and wifi and restrooms? So I book an aisle seat and ignore the zone calls and get in line near the very end.

Then I make up for being in some way possibly antisocial by helping someone with their luggage or something.

(As noted, I don't pay too much attention to it, but I do think they often board the tailies before the center on at least some airlines.)
