How to be a Rock DJ

So I've never been able to find a guide to being a rock DJ. All the guides out there focus on dance music, the technicalities of beat-matching and the artistry of live mixing. They are great and informative but it made it look like Rock DJing is easy or somehow invalid as there was nothing on the subject. After 15 years of learning the art of Rock DJing I can say that isn't the case, so I decided to write a guide. It's on wikihow, so anyone else can help improve it (cause I don't even pretend to be the authority on the subject). If you could pass the details of it on to anyone who is either thinking about becoming a rock DJ, or who is a rock Dj and can help add to it, that would be great.
