  • NYC: Tumblr kills StoryboardThe microblogging platform's first effort at journalism, or "marketing as journalism" came to an end after only a year. The general idea behind Storyboard was to create stories for partner publications (NYT, Daily Beast, Time) based on stuff happening on tumblr. Some of the stories were pretty great, but, as Hamish Mckenzie at Pandodaily notes, they "always had a whiff of marketing."
It’s sad for Tumblr’s hard-working editorial team that Storyboard has met an abrupt demise, but it might well be the consequence of a realization that platforms should stay away from doing their own editorial. That’s not their core competency, it’s not what their users turn to them for, and it ultimately can’t be seen as anything other than marketing in disguise.
