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.
Everything you need to know is linked to on that page I linked to.
Nothing is wrong with AngelList. AngelList is great. It was Bill Gurley's slimey VC actions to conspire with Nirav Tolia against the other Epinions founders and early employees that led Naval Ravikant to found AngelList as an alternative to the VC system.
For all the future founders on HN, the lesson here is to never do business with Bill Gurley. He's one of the reasons AngelList exists. I hope his lesser known reputation finally catches up with him and forces him out of Benchmark and out of the VC industry entirely.
