Well, not any more. We read how Google+ operates a real name policy. Going by the name Was Ist Das? over there would be in breach of that policy and would risk suspension of the account and our associated e-mail address.
As that e-mail address is one we use all the time, it seems best to pull the plug on our Google+ account rather than risk losing an important e-mail address. Google+ say they’ll start allowing companies on at some point in the future and when that happens we’ll hop back in.
