Please show a deleted notification when browsing to the direct URL of a deleted question. I find it vary annoying when I'm watching a question (pressing F5 every hour or so), and it simply disappears. I know that it was there, but now I'm treated to a page not found error like I typed something random into the browser. I'd don't need the explanation as to why it was deleted, although that would be nice.
Well, if you view the 404 page..
You'll note that it already says
Occasionally questions or answers may be removed from Stack Overflow for reasons of moderation: spam, off topic, abuse, etcetera.
almost all the time, the post was deleted by the author, by the way... it's very rare for it to be editorial or spam.
