Where's the pricing info coming from? It might be good to have a choice of sources under the Info tab, for when mtgox is getting DDOSed...
Indeed the pricing is coming directly from MtGox. I'll probably add other sources in the future 
Also, why does the Info tab have a "Terminé" button?
Woops it's a translation problem. It's French actually. I'll change that Also, would be nice to see even more info, like total money supply, difficulty ++ (more inspiration from http://bitcoinwatch.com )
Good idea ! 
Although I'm still wondering how I can add more infos without cluttering the interface.
Thanks for the feedback !
