Blog/collage metaphor

Reading this paragraph about collage's evolution as an art form tickled my thoughts about the similarities between blogs as a social media using other people's works hyperlinked to a post and collage as an artistic medium using other people's works glued to a board. No thoughts about it yet, just tickles.

The New York Times > Arts > Art & Design > Art Review | Romare Bearden: Life's Abundance, Captured in a Collage: "But Bearden recognized the medium as a potential literary vehicle, a narrative device, for synthesizing high formal values with a new strain of social history. His genius, aside from his poetic knack for piecing scraps of photographs and other tiny tidbits together, was to see collage as an inherent social metaphor: that its essence was to turn nothings into something, making disparate elements cohere; that it was about mixing and adding, a positivist enterprise."
