But what does dancing have to do with being a good DJ ? Are you saying only DJs that dance can be a good DJ ? If so why ? There's no logical correlation between the two things, because obviously if you had to dance to be a good DJ, everyone who dances would be a good DJ, and that just isn't the case is it.
I gave up dancing years ago when I discovered that a night's dancing left me virtually unable to walk the next day, it just wasn't worth it. But, although I say it myself, I consider myself to be a good DJ.
I don't promote any venues, so don't have my own event to DJ at, and can't offer anyone a spot in return if you know what I mean, so the 50+ bookings I get every year are based purely on my abilities as a DJ. I'm not claiming to be the best DJ around, or that I have the best, and rarest records, and acknowledge that there will be people who don't like my DJing style, or my choice of music, and occasionally I get it wrong, and screw up completely (Not very often though, fortunately). But, I know when I've done a bad spot as much as the other people in the venue do, because I feel crap about it. Fortunately I think I get it right nearly all the time, and this is evidenced by the repeat bookings that promoters give me, at a variety of venues, large and small, home and in Europe.
So the ability to dance has no bearing whatsoever on whether someone is a good DJ, does it !
