Right now, when you click on "New", worlds are sorted by when they were first published. This means that all of the awesome worlds created during beta are buried 100 pages back. I think that when you sort by "New", it should show you the worlds that have been updated most recently and not just published most recently. Otherwise, it's hard to find an older world that's still being updated unless it's trending. An alternate solution could maybe be adding a fourth filter called "Updated".
