The "visited" magic word does produce results when used in navigation, and the list does change from day to day. But you're correct, of course, that Special:Mostvisitedpages no longer exists. I'm looking further into what exactly powers the magic word's list.

But as I mentioned, this type of information in general is definitely something that we care about, and we know that admins care too &mdash; we're working on it!
