Rand, I thought one of the providers (Hitwise or Comscore) started to separate out internal v. external links. Perhaps those were just pure links, like when a link at MSN.com went to a search results page?
I also don't get the Facebook reference. Google has distribution deals - Google searches in Firefox still count for Google, for example. Is it just the fact that web results are at the tail of the page?
