Tumblr has been mentioned quite often lately. I miss it, too. For a while, its feed was a mirror of raw human creativity. The format did not encourage discussion, just the endless remixing of ideas. Technically, Tumblr still exists, although it lost its cultural significance. Of course, even in its heyday, it occupied a niche, somewhere between Twitter and Facebook, and was loved by some and ignored by many. My own old blog is still online, so I need to see what to do with it.
