Emily Bell left for the Guardian to become the director of a new centre for digital journalism at Columbia University, and let me congratulate her on the opportunity. Simon Waldman, described as the Guardian Media Group digital strategy chief by the Media Guardian, is leaving to join the DVD by mail service LoveFilm.

Now at the Telegraph, the Media Guardian is reporting that Will Lewis has been forced out over a disagreement with the publisher on the newspaper’s direction. What is shocking is that Lewis had just launched a new internal digital incubator just last November, the so-called Euston Project. He was named Journalist of the Year in March for the Telegraph’s scoop on the MPs’ expenses scandal last year.

My former colleague Roy Greenslade has details. It appears that Lewis wanted the Euston Project to be a standalone business and the publisher disagreed.
