the left side "Any time... latest... etc" list really, really, really benefits disposable blog-type sites over more mature ones. If something has not been updated in the past week (or day or whatever the range), it won't show up. On the other hand, even just changing a word on a page will get it listed.
So, if a page normally ranks #15 for a query, it can stay at #1 for "latest" just by making trivial pages changes and constantly getting the bot there via pinging or however.
And what the heck... "wonder wheel"?
