Increasingly, keywords seem to want to govern and organize our daily lives. They have become a kind of language without grammar, without modalization, dissonance, or doubt. They are isolated names which describe our environment, ourselves. YouTag offers us a device which, using the tags which describe the videos uploaded to YouTube as a starting point, allow us to suggest two words and generate a remix which superimposes the resulting videos. The mix of words becomes a war of meanings, and the video space is transformed into a battleground where no one meaning will triumph.
