I have no idea how much time you spend looking at Tumblr, or whether your Tumblr time is spent basking in carefully selected images taken by well-respected art photographers (or by photographers who aspire to join their ranks). If I'm being honest, that's a lot of what I'm trying look at, and you should follow shihlun, photographsonthebrain and bremser for this kind of content. In reality, though, this kind of activity must count for very little—I don't have any statistics to back this claim up, but I'm positive that this is not what Tumblr is used for, in a broad sense. For each post I've written in the Behind the Notes series, I've jumped into the cloud of rebloggers, wading through bizarre cursor behavior, garish backgrounds, unfathomable quantities of Bieber/weed/forest/dessert/Nike pics, and auto-playing background music (oh, the auto-playing background music!) to bring back these precious screenshots for you, the American Photo reader, to enjoy from the comfort of this very website. It's been a learning experience, to say the least.
