If I Vote to Close a question as a duplicate, I think I'm right in saying that the site will automatically generate a comment on the question - possible duplicate of blah-blah-blah.
I was just wondering whether it is possible (or indeed a good idea) to auto-generate comments for some other reasons?
The particular reason I had in mind is a product rec. One question just came up which is an obvious example of something falling foul of this - here.
It was a no-brainer for me to vote to close this, but it seems rude not to add a comment as to why. Especially as in this case, the user is new to the site. So I searched through and found one of @jimirings comments, and just copied and pasted - no big deal but not trivial as I had to copy the links too.
But it would have been nice if I hadn't had to go searching. Even if the site were to give me a checkbox to add a comment, with some default text proposed (pkay, I'm guessing this may not be supported).
So, can it be done and would it be a good idea to do so? As I say, I wouldn't propose this for all reasons, but I do think there are some that fit the bill.
