At the risk of sounding jealous, I can't quite see how MG could be that helpful to startup tech companies. I would think partners at funds like Google Ventures should have experience building things (e.g. Kevin Rose), or at least being part of a management team that facilitates the building of things.

That said, I enjoy(ed) MG's Apple coverage at TechCrunch, and wish him the best at GV. I just hope he stays long enough to make a meaningful impact on the companies he's writing checks to.
