Recently, everyone and their grandmother are trying to place steampunk in the grander scope of things. Most of pop culture has poked at it at this point. Many in the SF/F community gives the subculture a passing nod (or are slowly edging away, since, being early adapters by nature, quite a few in sci-fi are tired of it already).
