some - including me - have the feeling that outbound links in some manner may have a positive impact on the linking site itself. Maybe in such a way that with valuable outbound links a site looks more like an authority on a given topic.
It would also make sense for Google to assign greater weight to one-way links than to reciprocal links (whether outbound or inbound).
Other factors could come into play, too, such as the nature of the pages that are sending or receiving the links.
