I suppose Steampunk in the purest sense is a good label for those of us rooted firmly in the reign of the late Queen, God bless her, but not on the mainstream timeline*. But if anyone really has to label me, I suppose I would be more anachropunk (not that you'd know it to look at me).
*and that's another thing altogether; why do we still refer to time-lines when the reality seems to be closer to a time-funnel-shaped-cloud?
Presumably because things follow worldlines (geodetic or otherwise), not world-funnel-shaped-clouds.
