The death of Steampunk

I am appalled at the ongoing watering-down of "Steampunk", which apparently this year means "anything vaguely Edwardian or Victorian". It was bad enough in 08 and 09 when it meant "anything Edwardian or Victorian, with gears and/or brass paint". Next year will it have any meaning left at all? Does anyone making "Steampunk" costumes these days have any idea what _____punk means, or why "steam" is part of the name?
