It seems like we have a lot of of folks on the main site now, and every once in awhile I like to answer the "why did I get a downvote???" or "you hurt my feelings" or "you are elitists" type comments, which is almost exclusively due to a lack of research effort. I'm trying to save any potential new half decent users.
I don't generally bother on closed questions since the reasoning shows up.
Do we have any kind of specific landing page we aught to use when that comes up? I've looked at a couple of the help pages but I usually just use a screenshot of the tooltip when a question is voted down.
