There's talk here of "sounds" techno and personally I quite like the odd stand out sound to get my head around.
I haven't actually heard many of the mainstream dj's that are now playing techno in their sets, and it would piss me off if I did as I hate the bandwagonning aspect of it. But as has been rightly pointed out it's unlikely that people are instant techno lovers. This develops over time. Even those of us here are still developing our tastes as has been mentioned in this thread.
If it wasn't a genre crossing thing would it be as bad. My first taste in techno was for hard stuff, and only hard stuff, but I've developed a taste for other styles of techno... so am I bandwagon jumping? I don't think so.
I'd be interested to hear some examples of the tracks being played by JJ etc, as I find it quite odd to hear some of the names who get "slagged" here. I like a bit of Marco Bailey stuff in my sets. Along with the occasional Picotto tune, and some of these more "obvious" type tunes. I find that when I'm out in clubs I don't always want to be stroking my chin and nodding about an amazing production technique. If it makes me dance I'm up for it.
That's not to say I don't want to here "big" tracks all night either. Like everything a good balance keeps things interesting.
To get back to the point though, I think it's quite a good thing if techno's creeping into the mainstream, as long as it stays at the fringes. I don't want it to backfire, and all the "real" techno producers start making tracks so far up their own arse it is actually a turd by the time it comes out. And all in the name of "keeping it real".
