Breaking news: Outgoing links will help you with the SERP's. I might take time for the SE's to include the new find in their overall ranking algo of your site.
Example. On my web service related site I had listed keyword ranking results that I had achieved for one of my basketball sites. On this page I had displayed the Basketball related terms and had linked those important keyword phrases to each given SE so clients would easily confirm this on the SE's.
This page had no incoming links that were slightly basketball related. In fact the link anchor then had displayed "SEO Portfolio"
For about a month I was in the top rankings for those top keyword phrases until I ended this by adding the appropiate robots tag.
The site had no related incoming links.
On page I might have had about 200 characters worth of descriptive text.
Overall I had about 10 Basketball Terms linked to each SE keyword query.
To back this up: I have Awstats.
