Short version:

If you followed Pinterest’s Tumblr (blog) from inside Tumblr, you have to refollow it, because they made a new one.

Long version:

Growth! @Pinterest moving blog from Tumblr to onsite

The Pinterest blog has moved. Please visit blog.pinterest.com

Pinterest didn’t move off of Tumblr, they’re still on it. Their blog post wasn’t very clear.

But if you’re on Tumblr, you do have to re-follow it.

Why the confusion? They set up a new Tumblr. (If you wanna get technical, their old Tumblr was “pinterest” (.tumblr.com) and their new Tumblr is “pinterblog.”(.tumblr.com). Both are/were mapped to http://blog.pinterest.com.

How I figured it out:

Last night Pinterest tweeted a new blog post, that didn’t show up in my Tumblr dashboard. Confused, I visited it, and the Tumblr “follow” button appeared, despite the fact that I already followed Pinterest’s Tumblr. (Or so I thought. Mystery! Intrigue! *X-Files song.*

They might have done this because they wanted a group Tumblr, and you can’t make your primary Tumblr a group Tumblr.

They also changed their avi + theme. (Looks great!)

As of now, the old Tumblr still lives at http://pinterest.tumblr.com.

RIP, that tumblr/theme. 

So… just to recap: If you followed Pinterest on Tumblr, you have to refollow, coz technically it’s a whole new Tumblr.
