From a point of view of...

1. Get two records in time.
2. Mix.

Then yes, I suppose it follows the same format.

(Please note that the following is only IMHO - different people work in different ways and conceptualise differently, this is just what I think...)

The main difference is that with Techno you tend to aim to hold your mixes for much longer. That's because there's a fundamentally different mixing philosophy at work.

With most electronic music (Breaks, D&B, House, Trance etc.) tunes follow a standard structure. You have an into, a tune and an outro. You mix the intro of one tune into the outro of another and so on, into a long chain of music. So far so good.

With Techno, because of the very abstract and rhythmic nature, you can play two tunes at the same time and end up with a whole that is greater than the sum of it's parts. In this sense, I see DJing Techno as more a case of inter-weaving two walls of sound to create something new.

Apologies if this all sounds rather pretentious, but that's just how it works in my head. ;)
