What is the connection with audience participation?
Audience participation typically involves spontaneous acts or outbursts. When people applaud, boo or laugh, it is a moment of spontaneity that occurs and then disappears forever. When a reader cries upon reading a poem, poignant as that moment may be the tears soon dry and are lost. The comments written on the margin of a book, disappear when that book is trashed. With audience-sourcing, those moments of inspiration or emotion are recorded and have a duration that may extend into eternity.
