Personally I would like to see CFB back in hear and hear more on the tangle debate as I have not seen his retort to the inevitability of the tangle diverging. That sounds like a game changer to me and if true will make IOTA a complete waste off effort as well as time and resources. Unless it is just a money grab which in that case it seems to be working.
TPTB_need_war and me tried to discuss Iota but failed to sync on the initial stage (definitions), so further debates didn't make any sense. This is why I ignore his critics of Iota/Tangle - we simply speak different languages.
