As regards to the mic discussion i'm not fussed either way, if there's one there i'll use it, if there isn't, just play the records, As regards to virtual D.J's that would be fun to see a hollogram beind the decks .....My pet hate as regard D.J's, is D.J's who stand beind the decks with their hands in their pockets looking miserable, I think a good D.J is one who looks as though they are enjoying what they are doing, entusiasm is infectious, and a good D.j can definatly influence a dancefloor.
