Are the following two big-list questions posted by me welcome here?
Was sind gute Zungenbrecher im Deutschen? / What are good German tongue-twisters?
German words with interesting etymology
I think that these are question that could have a edifying collection of answers, but that they are close to the borderline, so I wanted to put them up for discussion.
I propose that you upvote my question here if you welcome the questions, downvote my question here if you think that they do not belong, and write an answer if you have a more nuanced response.
