Peter Lunenfeld (wikipedia), professor in the Design | Media Arts department at UCLA, argues in a New Scientist op-ed piece for the importance of what he calls “meaningful uploading”, which is still difficult for most people since “for the past half-century, much of the world’s media culture has been defined by a single medium – television – and television is defined by downloading.”
“What counts as meaningful uploading? My definition revolves around the concept of “stickiness” – creations and experiences to which others adhere. Tweets about celebrity gaffes are not sticky but rather little Teflon balls of meaninglessness. In contrast, applications like tumblr.com, which allow users to combine pictures, words and other media in creative ways and then share them, have the potential to add stickiness by amusing, entertaining and enlightening others – and engendering more of the same. The explosion of apps for mobile phones and tablets means that even people with limited programming skills can now create sticky things.”
