In 2010, Sun Microsystems CEO Jonathan Schwartz became the first Fortune 200 executive to quit his job with a tweet. And not only did he submit his resignation in 140 characters or less, he did it via haiku: "Financial crisis/Stalled too many customers/CEO no more" [source: Vance]. Style points for Schwartz.

Schwartz' resignation from Sun was hardly a surprise. A week earlier, Oracle bought the company, and its outspoken CEO Larry Ellison made it clear that there wasn't enough room in the Silicon Valley firm for two chief executives.

After toiling away at Sun for six years trying to convince companies to buy its servers and networking equipment, Schwartz made a 180-degree career switch. He launched a Web startup and smartphone app called CareZone that helps caregivers keep track of doctor appointments and medications for elderly loved ones [source: McCracken].
