I was wondering what the purpose was for listing the user or users involved when a question is closed.
Is the person who asked the question expected to use that information in some way? Since there's no personal messaging feature in the SO network, I'm not sure why the users involved in closing are a) displayed and b) linked to their profile.
Is the user asking the closed question expected to take some sort of action with those users? If a question is then edited and/or re-opened, the user isn't expected (or encouraged) to go around and contact those involved in closing the question. However, displaying and linking this information would seem to imply that further action should be taken.
To me it seems like the biggest downside in listing the users that voted to close a question is that the user asking the now closed question gets their feelings hurt (usually new users), and goes off on a downvoting spree in some sort of retaliatory move.
I'd think that simply stating that the question is closed would be just as effective without listing the users, and prevent any malicious revenge downvoting. Or, only show those involved in closing the question to mods, or those with a certain amount of reputation.
