LinkedIn has provided the White House with some of the trove of data it has collected about its users’ activities in the job market; the data have been used in the annual Economic Report of the President. Earlier this year, a former LinkedIn executive, DJ Patil, was named to the new position of chief data scientist in the White House. In July, Hoffman organized a meeting for people involved with Obama’s new foundation on how to better harness the power of social networks. His list for dinner with Pincus included the question of what to discuss at that meeting.

The segment of the market that uses LinkedIn != the market.
