I think from the begining 'techno' was misrepresented by the press... by 'techno' artists and djs and labels however it does mean just that - groundbreaking electronicdancemusic...
Hence once it's classifiable it's classified: acidtechno, techhouse, hardtechno, detroittechno, electronica, tribaltechno, minimaltechno...
What I'm getting at is that while they're part of the techno unbrella, the simple word techno by itself actually comprises things whch aren't able to be classified by other musical formula's yet...
Techno paved the way for most forms of modern dance (ie. techhouse, electronica, breaks, jungle, hardhouse, trance you name it) but eventually they end up being something else entirely, mabye that will always be the case, but you can be sure to know that 'techno' will always push foward.
I think this is where some people think it's techno snobbery, but it's really just simple catagorisation. Oh and masters level research and development
Oh, and I forgot to mention (just to piss the house kids off) that house owes much to techno - it was the detroit boys who gave House the solid kick and tight drumprogramming, it was techno that gave all that westcoast styles their techniques and proghouse all the ehterial styles... ahem.
All good tho.
