I used wikipedia to figure out what the top 10 spoken languages are right now. I'm going to increase our visibility on the engines. I would recomment to not take the numbers from wikipedia but maybe from the local user groups in bitcointalk (sorted by number of posts) .. and also advertise the translation there ..
Well, I would put it there, but hardcore bitcoiners are like anti-bitsharers. I did put the job posting on g+, twitter and a couple other spots though. The more we spread the word, the more cultures will be able to utilize the platform. Thanx xeroc
