It’s a minor cosmetic change but quite a significant one – earlier today, Twitter dropped the (increasingly infamous) ‘What are you doing?’ question from above the tweet box on Twitter.com and changed it to ‘What’s happening?’

Twitter: What's Happening?

Biz Stone notes in his write-up about the tweak that it’s unlikely to change the way anyone users Twitter, and this is certainly true for existing users. However, newcomers to the service will instantly be presented with what is quite a significant introduction into exactly how they can interface with the platform, specifically because of what Twitter has become.

No longer is it just a simple mobile status update service – it’s a massively important tool that’s becoming more and more significant in both the mainstream media and within the general populous, with each now able to wag the tail of the other.

Even if that sentence doesn’t actually make a lot of sense, just go with it, as this is a unique time in our history. After all, nobody is checking the reaction on Facebook after a major news story breaks.
