I don't like Joan, Joanne and Joanna at all. They sound really heavy and dense.I love Jane but not quite as much as Janet. It isn't on there but guess what I love Janice (or Janis) too.Jean and Janna are just OK.
Me too, actually :) I like the sound of it a lot. It is hard to separate it from the datedness but Janet is equally as dated to me and I prefer it to Janet.
