I ran across Aardvark the other day and quickly slotted it into the doesn't-apply-to-my-everyday-stuff bucket. Until I started using it for cleaning up blog entries before printing (as described on the aardvark site, you can easily get rid of surrounding fluff on pages that don't have a printer-friendly view, or further reduce pages whose printer-friendly view isn't as printer-friendly as you'd like it to be). Then I tried modifying the page prior to saving it with Furl and was happy to see that my saved copy was, in fact, the reduced version of the page. Cleaning up every web page wouldn't be worth the effort, but every so often, there's a useful tidbit that's embedded in so much crap, that it just begs for Aardvark's "isolate" command.
