The future of corporate communications? 140 characters, apparently. The now former CEO of Sun Microsystems made history this week by offering up his resignation via Twitter. "Financial crisis/Stalled too many customers/CEO no more," Jonathan Schwartz told the world, haiku-style.

The resignation came in the wake of Oracle's purchase of Sun. According to The New York Times, "Oracle's chief executive, Larry Ellison, is not especially fond of Mr. Schwartz. In an interview last week, Mr. Ellison said he fully expected Mr. Schwartz to resign rather than play a role in the combined company."

Schwartz served as the head of Sun since 2006.
