Thumbing (2010) is a video documentation of a Youtube intervention, or online performance. A recurring theme in JODI’s oeuvre is to flood an online platform with garbage. A feature on the popular video-sharing website YouTube was to video-comment. JODI posted numerous video responses, of them just holding a thumb very close to the camera for a few seconds. Thousands of these clips were distributed on YouTube, filling the site with an endless series of these useless “pokes”. Eventually this practice was converted into a participatory event that was performed at openings and events where they would increase their proliferacy by inviting the public to produce these “thumbing” videos.
