Little traffic in zoom?

Good afternoon, I have noticed that according to level up there is little or almost no traffic in zoom. As of NL25 in fact there are hardly any players. I am playing zoom in NL10 because I find it more comfortable to have fewer tables open to play the same number of hands but I would like to know if the regs do not play zoom and why. Is there any difference why you do not like it? Thank you!
