Personally I don't care much one way or the other since I don't normally put a ton into comments besides trying to clarify a question or answer.
I can't find the reference materials (someone else hopefully will shortly), but I know Jeff has mentioned before that he's not a big fan of comments because they add noise and one of his prime goals is keeping
Signal > Noise.
So I thought we should discuss it here on meta, and hopefully someone officialish will weigh in on it as well:
Should comments be treated the same as other posts, or are they tertiary and unprotected?
It's unlikely a good answer or question (which is still on topic) will be deleted by a mod out of hand, and even if it is 10k+ users can still see them.
Would it make people happy if 10k users could see deleted comments?
