Jonathan Schwarz, now the ex-CEO of Sun Microsystems after it was finally acquired by Oracle, decided to end his tenure with a tweet.

Schwarz said on his Twitter account: "Today's my last day at Sun. I'll miss it. Seems only fitting to end on a #haiku. Financial crisis/Stalled too many customers/CEO no more".

Jonathan has, at press time, 7,519 followers on Twitter and regularly updated his bog when he was the CEO of Sun. He's regarded well throughout the industry, largely because of his open manner. His Twitter account is OpenJonathan.

In his last bog entry at Sun, he wished the combined company the best of luck. And he's not going to go away, he said.
