Yep... and an easy way to add a tag while typing without needing to slow down to do it.
I just realized too a problem with backlinking for this. For backlinking to work.. the page must exist. You can make a reference to a new tag/keyword/page what-have-you, but until you click it and edit something, that page doesn't exist and so you can't click on it to find its backlinks. The obvious solution to this is to make links in the index (and search tool) to un-initialized pages.
