Today, on C.SE, I reviewed some 'Late Answers' and First Posts. I was not even near my daily vote limit. And yet, I was given a message that said
comments disabled on deleted / locked posts / reviews
It seems I was not the only one either: Why are comments now disabled on "first posts" reviews?
The workaround, of course, was simply to go back and provide the guidance - but was this a design or a bug? If it is design, why would you want to discourage the feedback? Especially with first posts, there is often a high percentage of 'didn't read the FAQ' usage, which can best be addressed by gently providing guidance. (e.g. "Unfortunately, this doesn't answer the question" or "This reads like a comment" or "This really isn't on-topic here - can I suggest you checkout our [faq]" etc...) Timely first post guidance goes a long way towards making good users.
If it was a bug, was other functionality silently rolled out?
