NvyUs and zerojay, please step outside and solve your dispute.
Personally, i'm against. English is the language of the internet, just like http is what you use if you want to see a webpage. Because generally PR people are required to speak at least english, i think there are really few people that could add more information but can't because of the language barrier. Keep in mind that normal developer employees are barred by NDAs from revealing anything important (right, nokia people?).
Sure, maybe some independent devs would have it easier if they could chat in their own languages. There's nothing stopping them from creating their own unofficial communities. But i don't think they will get very far without basic grasp of english (because, let's face it, we're not writing shakespeare here, so no one really needs advanced skills)
So, bottom line: everything official in english only. This would create a "master" message to compare against. Since there are certainly more than 2 english speakers in any other language community, distortions are easy to fix by using the english original. And sub-communities (preferably not affiliated to maemo.org to avoid confusion) all you want
