"A year ago, Tumblr did something unprecedented," Tumblr founder David Karp writes about the editorial team the blogging service assembled, which fed its "Storyboard" project.

Tuesday night Tumblr did something not unprecedented in the world of publishing: It got rid of its editorial team.

"What we’ve accomplished with Storyboard has run its course for now, and our editorial team will be closing up shop and moving on," Karp writes.

Tumblr told Kelly Faircloth it's laying off three of the team's four members. Peter Kafka and Catherine Shu both say Tumblr is focusing on profitability, a possible motivation for the layoffs.
