4e received a mixed reaction from my gaming group. Some definitely want to switch, while others definitely dont want to switch so we're sticking with 3.5 by default (everyone is happy enough with 3.5 as well). I'll be running 4th Ed with a second group (some newbies, some old friends) every now and then though. Re the "booing"/gaming snobbishness, I have noticed that many WoD players at conventions here in Ireland turn their noses up at D&D as being a "kids/munchkins" game...not all mind, some play either game without a problem.
