Beat point 1.
The most important fact you should know is: In techno, your beats are one of the defining factors in track saleability and grasping audience attention. For example, in a club the DJ will mainly play a techno song with a good beat- people want a good time and a good thumping track is the key for crowd pleasure- guaranteed.
If you make your own music beats and your beat is similar to everyone else's why should the DJ play yours? If on the other hand, you have made your own beat, and it is a bit different- having some cool sounds interwoven with the common beat- it will arouse interest.
Your own beat can also be the basis of a good idea. There has been many artist that have said "I started off with a good bass drum".
To make your own music beats could also BE your own track. Adding various effects and various sounds could carry the track all by itself. Underworld's "Born Slippy" is a testament to this idea. I know it has some chords at the start, but utilising their own beat, with various effects added, made this a club classic.
