b) Perhaps it's dumb, but it's reality. If you write a text in german (to a german audience) in Wikipedia, german courts will judge you - even if it's done at a server in Florida. Perhaps the court is not able to force the server to put down the text, but it's able to judge you. If you are not in germany, that should be no big problem - but as german person or visiting germany, you will get problems. This happened before. And I strongly expect, that this is the case not only in germany. Bye, avatar.
Why would writing text in German imply that it's written for a German audience and make the German courts able to judge you? It's not as if there aren't other German-speaking countries...
