I was an engineer at Netscape through the period this documentary covers and it's one of my favorite (though bittersweet) documentaries. I wasn't involved in the development side, so my involvement with most of those featured was quite limited, but . . . what a great piece. I'd also couple it with (what I'm sure has been mentioned elsewhere, but I've not read that far, yet) Revolution OS (
