No Huffington at Huffington Post

Arianna Huffington, who helped found The Huffington Post in 2005, is stepping down as editor-in-chief of the pioneering Web publication.

In a note to employees on Thursday, the 66-year-old said she would be focusing on her new venture, a health- and-wellness start-up called Thrive Global.

For the first time since its founding, The Huffington Post will be without Huffington. No successor was named.
