Here's to the screaming ones. The chair-throwers. The death-threat makers. The imperious gazers. The ones who see things differently — and will stare you down until you do, too. They're not fond of rules, especially those outlined by the human-resources department on "treating your employees with respect." And they have no respect for conversational decibel levels. You can cower before them, hide from them, quote them behind their backs, or vilify them. About the only thing you can't do is ignore them. Because they're so damn loud. They've worked at Google. Apple. Microsoft. AOL. They've ruled the industry — or they've failed, loudly. Below, we present you tech's 10 most tempestuous bosses — the ones who scream different. While some see them as sociopaths, Valleywag sees genius.
