In case you haven't seen this potential tool, Spike Hall mentioned PurpleSlurple as a way to get better URL's in your writing, so that readers need not hunt around long pages to find a specific reference.
I add PurpleSlurple to the weblogging tools I find indispensable. If we are to be hyperlinked let the links be granular. A link to a granular address takes you to a very close approximation of the exact words, the exact picture in the refered to document. A link to the document as-a-whole, even if as short as a 5 paragraph weblog entry, causes too great a break in the reader's train of thought.
