I don’t mean to always disagree and in the context I may be totally wrong, but my knee jerk reaction is, I do not think we really have a problem, at least not to me personally. It is more interesting (to me personally) to let the person making the question and answer use the terms they think are reasonable. We can always ‘google’ just a bit to see what they mean, while retaining the colorful expression that originally preserves the full twist of the question/answer.
For example I always giggle when one of the persons on this site asks a question with strange words I can’t comprehend. I usually like their questions and answers so I use him as an example in a positive sense as being good example for this site.
In Genesis 49:24, what is the meaning of the phrase מִשָּׁם רֹעֶה אֶבֶן יִשְׂרָאֵל?
Now I have no idea who Ya'akov or Yosef are so I giggle to myself while associating them to the English names after reading the related verse. I feel like I had a good experience because the person forming the question is tickling my brain and its fun. Should I edit the question so that ‘any English speaker who is interested in this content would be able to understand what it means without additional research’? Maybe, but (personally) I prefer not. It makes me understand a few things about the question. Hebrew is important to him, so I should at least know that when trying to answer. What’s wrong with a little personality? I may be wrong, I get the feeling I should not be making rules around here but others should and then I can learn to follow a bit better, I am only giving my feeling about it in terms of preference.
Again when somebody uses the phrase ‘Tanakh’ in a question are we to enforce an English word that most people would understand instead? No, I do not think so. I would probably not use that word and prefer more commonly used English names. Forcing an English translation seems unnecessary.
All the No's, Not Even's, Not so fine's and Confusing's in your list I can understand but actually prefer them as they are as indicating the personality twist of the original question and answer that help understand the overall spirit and meaning conveyed by each. If we become word police we may as well censor broad vocabularies that make people refer to a dictionary or those that use any sort of palaver to express a slight gradation of terms. I personally loathe any kind of censorship in any kind of way. (Down-voting can take care of that, or when when truly intentionally offensive, deleting it.) I repeat this might not be the best policy for the site I am only explaining how many people might feel about things that should be 'considered' when attempting to make any policy.
