Silbermann suggests that collecting online is a form of self-expression for people who don’t create. “If you walk around Brooklyn and ask people how they express themselves,” he said in a speech at New York University, “everyone’s a musician or an artist or a filmmaker. But most of us aren’t that interesting. Most of us are just consumers of that. And when we collect things and when we share those collections with people, that’s how we show who we are in the world.”

Not everyone buys into this, of course. Here’s The Awl’s co-editor, Choire Sicha, for instance, on the subject of rebloggers who fancy themselves curators: “As a former actual curator, of like, actual art and whatnot, I think I’m fairly well positioned to say that you folks with your blog and your Tumblr and your whatever are not actually engaged in a practice of curation. Call it what you like: aggregating? Blogging? Choosing? Copyright infringing sometimes? But it’s not actually curation, or anything like it. . . .” To which a commenter added: “My Tumblr isn’t so much curated space as it is a symptom of deeper pathologies made manifest.”

According to lunar scientist Paul Spudis: For forty-odd years, the flags have been exposed to the full fury of the Moon’s environment – alternating 14 days of searing sunlight and 100° C heat with 14 days of numbing-cold -150° C darkness. But even more damaging is the intense ultraviolet (UV) radiation from the pure unfiltered sunlight on the cloth (modal) from which the Apollo flags were made. Even on Earth, the colors of a cloth flag flown in bright sunlight for many years will eventually fade and need to be replaced. So it is likely that these symbols of American achievement have been rendered blank, bleached white by the UV radiation of unfiltered sunlight on the lunar surface. Some of them may even have begun to physically disintegrate under the intense flux.
