This paper reports findings from four related studies of the "Tenori-on" as it appears on YouTube in order to consider Web 2.0 as a performance space. A quantitative analysis of returns for "Tenori-on" attempts to model how posts achieve and maintain popularity. This analysis suggests sustained posting and engagement amongst users rather than initial product launch enthusiasm. A content analysis of the videos returned demonstrates a very different response to the launch of other technologies like the iPhone 3G. A grounded theory explores comments to the most viewed video returned which was a post by the artist Little Boots. A range of comments indicate virtual applause and suggest that YouTube has been appropriated here as a space for performance. Finally perspectives from critical theory are drawn on to consider the meanings of the Tenori-on in this user generated context and the ways users creatively resist the most obvious affordances of the device.
