pmarca and gurley hate each other. pmarca is definitely the investor I would take money from. In fact, its funny you mention him. He's been hugely useful to Lyft (and his other investments) since he's "purchased" so much "goodwill" among The Who's Who of journalists covering Silicon Valley. As John Doerr once quipped, "No conflict, no interest", and pmarca has learned this lesson well. Every investment he's made in journalism companies is a conflict of interest that earns him interest. Investing in Silicon Valley's loudspeakers has given him a steady stream of positive submarine pieces in favor of him and A16Z and unfavorable pieces against those companies that compete with his investments.
