- Official reference for “don't leave ‘thank you’ comments”
- Is it acceptable to write a thank you in a comment?
I think there's general agreement that thanking a person for a good answer isn't what comments are for. However, if a user does thank me for an answer, may I acknowledge it with "You're welcome!" or "Glad I could help!", or is this kind of comment frowned upon since it doesn't contribute meaningfully to the discussion?
In the past, I've usually ignored "Thank you" comments for that reason, but every time I did so, I felt it was somewhat impolite of me (especially if my answer was upvoted and accepted).
