A few days earlier, I came to know about this feature of SO. I am not sure whether it was present earlier also or has been added recently.
The number of votes for each question/answer can be clicked and it shows number of UPvotes and DOWNvotes separately.
However this feature is not there here in Unix and Linux site.
I think that feature is good and can be introduced here also.
P.S.: I know I am not a very frequent visitor here, still wanted to put forward the suggestion, because this site along with AskUbuntu has helped me in some real problems.
