Personally I'd prefer no leadership att all. The more decenentalized the better imo. Of course we need people that are active in the community and speak in favor of bitcoin but I don't think we need anymore organizations that speak the word of bitcoin. Let the market do it's job. When it comes to MtGox the market is doing just this with the increasing spread between Gox and other exchanges. Think it's working perfectly in that aspect. If MtGox problems increase the market will keep "judging" it in the way it requires.
I don't want to put rpietila down in anyway. His posts are what made me join bitcointLk in the first place. I just love the posts about how 10btc will make you super rich etc. Also his trading skills are far superior than most in the other wall thread.
