Site co-founder Biz Stone explained the reason for the switch is that Twitter has now become less about personal updates, and more about what’s going on in the world.
In a blog post, Stone said: “Sure, someone in San Francisco may be answering ‘What are you doing?’ with ‘Enjoying an excellent cup of coffee,’ at this very moment.”
“However, a birds-eye view of Twitter reveals that it’s not exclusively about these personal musings. Between those cups of coffee, people are witnessing accidents, organizing events, sharing links, breaking news, reporting stuff their dad says, and so much more.”
A fair enough point. Also, “What’s happening?” sounds a bit trendier. More so if you stuck a “dude” on the end.
Although “Why don’t you stop wasting time and get on with some work?” might be nearer the truth still.
