Every social media service gives us the power to write updates – tweets, notes, blog posts – public texts where we are free to express ourselves in anyway we like. And so Chapter 4 of The Psychology of Social Media begins with the Twitter Joke Trial – a classic case of online disinhibition, where people say things online they might not say in the ‘real world’.
A sense of invisibility when posting is noted, which led to a discussion of the Facebook News Feed outcry, and a re-examination of the privacy paradox. Users’ frustration over losing control of their updates’ publicity, yet continuing to post personal information publicly, is interpreted with regard to the ‘Facebook iceberg’.
Algorithmic timelines threaten us with obsolescence unless we post popular updates, and as a result our attention is focussed on the visible tip of social media activity. Furthermore, while social media prefers current content, it nevertheless has a permanent quality: even when updates are out-of-date, they are still indefinitely searchable.
Hence, Chapter 4 concludes by examining how we deal with the temporality of our updates. While we don’t want them to fade from view over time, having a lifetime archive publicly available forever can be an unpleasant experience: the past collapsed onto the present.
