Jack Dorsey, the founder of Twitter and the face of the company for 15 years, has announced his resignation from the site, effective today. Chief Technology Officer Parag Agrawal will take over as CEO.

Dorsey naturally announced the sudden resignation on his Twitter account, sharing a screenshot of an email he sent to the company with the news.

"I want you all to know this was my decision and I own it," he wrote. "It was a tough one for me, of course. I love this service and company… There aren't many companies that get to this level. And there aren't many founders that choose their company over their own ego."

"I want to thank the Board for their confidence in my leadership and Jack for his continued mentorship, support, and partnership," Agrawal said. "I look forward to building on everything we have accomplished under Jack’s leadership and I am incredibly energized by the opportunities ahead. By continuing to improve our execution, we will deliver tremendous value for our customers and shareholders as we reshape the future of public conversation."

Twitter stock rose after the news was released before trading Twitter stock was halted. Online, Twitter users took the opportunity to fire off some hasty jokes about Jack getting off Twitter.
