If you, my peers, have decided that a question should be closed, why oh why does it still show up in the list of questions on the main Serverfault page? Even if this continues to be the default behavior, it would be nice to have an option -- like we do for "ignored tags" -- to completely hide these questions, since most often they've been closed for good reason.

EDIT: Based on the comments so far, I'd like to emphasize: I'm suggesting an optional behavior, not a change in the default behavior. I understand that some people may want to see closed questions. These days, most of the closed questions I see are closed because they're pretty low quality, and I would be happy to ignore them, but there are certainly exceptions.

Simply tagging closed questions as "closed" would let me do what I want using the existing "ignored tags" filter.
