I DJ in SL and I use 192.
As far as what I don't like? Like many of you, "DJs" that talk on and on irritate me. I don't go to a club to hear people yak away. I'm there for the music. I, personally, do not voice, but I blab a lot in local as does everyone in the sim I work. Gestures can be VERY distracting. My hostess will mention tipping maybe 2 times in a 2 hour set. I may say something about the guests tipping her. We don't get nor ask for multiple tips from any single person. Should they request a song after an initial tip then tipping is expected for that.
