I have also wondered a lot about the incompleteness of "link:<mywebsitesite>" command. Google's documentation is not very elaborate regarding that. Google webmaster on the other hand gives a more complete link of external links to the site. My guess its deliberately incomplete because of: 1) Google's competitor search engines (bing, blekko, duckduckgo) to not easily get Google's Internet graph. 2) Competing websites should not get each other's complete link graph.
