I think it is interesting that the author mentions, "I want to see the candidate's twitter feeds, Facebook pages, LinkedIn profiles, activity on mailing lists and github, etc."
I found TalentBin.com comes the closest to solving this need. This is a screenshot that shows all the profile information accessible on a TB profile- http://screencast.com/t/DgePgGRj
Not only do you get access to what they are tweeting about, but you also can see their personal blogs, google+, Meetup, and Stackoverflow? http://screencast.com/t/SfFqIMXWIzlg
So far nothing comes close to Talentbin in terms of information quantity and quality.
And if that isn't enough- TalentBin.com recently added the entire patent database. Soon will come the day where we hire by looking at only implicit web information and resumes are long forgotten.
