Which language should tags be in?
I just skimmed through our current tag list and found, that all but falle currently are in English.
I propose to use English tags in the first place.
I'm not sure if German synonyms are possible. I guess that is a technical question i.e. better posed at https://meta.stackoverflow.com/
And please give a good English translation for falle. I think it is a very important tag.
Is it pitfall ?
