Techno is still very much alive. Judging by global (and local) sales, it's not in any danger of dying out soon. I think that the media's flirtation with all things Detroit in the later part of the '90s led to unrealistic levels of support, but to be honest, it was mainly the more house end of the djs (Pullen, May...).
And locally, there's always been things to go to - early shit including Rebal Alliance, Underworld, Move, Straylight@Box, internationals, Superfly, Fu, and the sparse bamboo offerings

The main ingreedient is support.
You need to actually participate if you want a scene. I think most people would like to see the local techno community grow and prosper, but to be honest, it's already fairly large, it's just as Slug says - if everyone turned up, techno parties would be packed! We have to occasional full house, but if this happened all the time, it'd create a chain reaction and would gain the energy of the d&b scenes or even house...
So next time you're debating if you should come along to a techno gig, remember, everyone there will have one thing in common - love of quality music.
Also while it may appear that Miles and me are 'too cool for school'

we're just in the same boat as most other techno-heads, fairly reserved... we are nice people, honest!
