And when you look at Marc the capitalist, rather than at Marc the ideas guy, the hero-worship becomes a bit more difficult. I certainly like the way that he’s dragging Silicon Valley into the world of philanthropy, where it’s historically been very weak. But a lot of my own Wired story, last month, can be read as a push back against the IPO culture which Andreessen, almost more than anybody else, has managed to create.

“Silicon Valley is full of venture capitalists who have become dynastically wealthy off the backs of companies that no longer exist,” I wrote in that piece, and Andreessen is Exhibit A if you want to look for such a person. His first company, Netscape, lost the Browser Wars and ended up getting sold to AOL. His second company, Loudcloud, was (to be charitable) too far ahead of its time, so it “pivoted” into something called Opsware; eventually Andreessen managed to sell it off to HP. His third company, Ning, was even less successful, and ended up buried somewhere in Glam Media. None of them exist today in any recognizable form; none of them ever made much money; and none of them even really made it as far as building anything approaching a permanent income stream.
