Great post planet13. :)
Some sites are scholarly, and you would expect university professors to link to them...
Shaking things up a little... Is it possible that dot edu links aren't such a good thing for a commercial site, IF a dot edu sends Google the signal that your site fits into the Scholarly Query Bucket and not the Commercial Query Bucket?
