My favorite trading platform is that one cafe in my town that has wifi. It also has coffee, beer and at least two bitcoin enthusiasts.
Maybe I should open a cafe, accept bitcoin and morph it into a traditional trading floor. Back to the roots!
Please do. My favorite trading platform is my private-club-cum-office in my town. It also has coffee, white wine, all cutlery made of silver, and biweekly meetings of the Finnish bitcoin elite. I am running a daily volume that was only exceeded by Mt.Gox well into the 2011

wow! Cafes are also traditionally used for gossiping and sharing news. So that's also a good fit for the bitcoin community
