for some handy stuff like:
- Using links as a kind of tag; creating blog pages that list all pages
containing a given tag/link or not containing some other tag.
- Subscribing to mail notifications whenever a change is made to a page
that is a backlink of page foo. Ie, "Please notify me of changes in all
pages that link to my home page in the wiki"
- Locking any pages that are linked to from a particular page, so that
lists of locks can be exposed in the wiki.
