Raised an interesting point there Winnie - gave Chalky n me something to disagree over tonite
A dancer whether female or male certainly has potential to make a good DJ in theory, (goes without saying that top DJ's not compared in this post), as they may know what does or dosen't work on the floor, after all they are the one's the DJ's aim to please. A DJ's dancefloor success would generally influence the booking's they get.
Of course there is so much more to being a DJ though - having a good ear for the right sound at that time, able to adapt but not alter your style of DJing to work the dancefloor. Obviously the ability to put a set together so it flow's is above all imperative, as nothing worse than a mish matched set Confidence in what you play is also paramount - even if hall only 1/4 full or not many dancing as doing an early spot - they must show energy and passon for what they've got on the deck's nothing worse than seeing a DJ on stage looking fed up. Personally a DJ who is prepared to put time and effort into putting together a set that offer's something that little bit different, in other word's - putting their own signature on their set.
So in answer to your question - Yes n No
