They didn't seem to have much original to say. Everything they discussed could have been gleaned from Techcrunch, Mashable, etc.

I wonder if their money and network will be enough to compensate for lack of (real) operational experience when they court top tier startup teams.

Reading PG or Thiel, or watching Andreesen's presentations at http://ecorner.stanford.edu, there's a world of value beyond money that they bring to table.
