Goodfellas you mention authority sites, and I agree, their links are more valuable than niche never looked at directories, but they often disguise their links so as not to pass any PR, so it is left to whether they might deliver some traffic.
Exactly. If an authority site sees something "worth linking to", they'll probably expand their own site and add similar content themselves rather than helping a potential competitor. In the case that they do link, they use every method possible not to provide link juice. For example, outbound links in Guardian.co.uk actually redirect through URL shortening services like tinyurl.com!
