"Gouge" is a term born out of the U.S. military. If you have the 'gouge' on a subject, you have an insider scoop or are knowledgable about that subject. The poster is asking for a site with 'interview gouge' much like this US webpage:
http://www.aviationinterviews.com
Perhaps the good people of PPRUNE would consider putting in a special section for interview gouge
