I have previously posted some queries in GENTLE and mentioned them in my room.

Anyway if an effort to created some queries relevant to HNQs has moved here, let me try a few more.

Questions which were and HNQ and were closed at some point (as there might be some correlation between getting closed and questions of lower quality)

I do not think that from SEDE we can find the posts that were removed from the HNQ by editing the title - since the edit might have come after leaving the HNQ list. Anyway: Questions which were in HNQ and have $ in the title
