One the one hand, the "benevolent dictator" model has shown itself to work pretty well for Linux, compared to some major failings of the "committee" model on other projects. On the other hand, does anyone think the fact that "major" changes can be done by one person who is "just going all alpha-male" will potentially spook people? I mean, I doubt too many people here on hn have a problem with Linus' personality. I imagine most of us appreciate his sense of humor and respect him as a penultimate hacker... I'm just thinking about starched-shirt types who call the shots in big businesses -- can you imagine being an IT manager and trying to explain to your boss that after 15 years there's a new major version of the Linux kernel because "well the head guy got tired of calling it version 2."

Edit: Penultimate apparently doesn't mean what I thought it meant, so, what I meant was "...respect him as a very good hacker...".
