A correspondent from Valleywag wrote last week to ask if I saw anything interesting in the Twitter decision to change its prompt - from 'What are you doing?' to 'What's happening?'.
I do think this is interesting. My impression is that Twitter has become steadily more discursive over the past few months, with people maintaining threads and introducing a great deal more interaction, rather than posting isolated tweets. As a result the focus has shifted from the individual to the group, and a more open question is required to capture this emphasis. 'What-doing' looks inward. 'What-happening' looks outward. It's a natural development, it seems to me.
I love one of the reactions to the Valleywag post. Someone suggests that a much simpler prompt will emerge one day: 'Sup?'
