temporal uniqueness. Art in a museum is locked in a gated vault, like a website is locked to a version number. Ephemera is when you walk past your favorite street art and a piece of the pasted image was scraped or defaced, or when another artist or rando with a pen or a can added something in response. An ephemeral website is one that you hope will be different when you refresh it. There's an element of chance and the content is the reward. To an extent, aggregators have long embodied this characteristic I feel.
