Interesting article from the Washington post on Twitter’s changing its catch phrase
Twitter has implemented a small change today, which by comparison to Retweets and UI redesigns isn’t such a huge deal but it’s definitely worth mention. Twitter’s prompting question above the box from which you Tweet from has been “What are you doing” since the microblogging platform launched. Today, it’s been changed to “What’s Happening.”

Seems like semantics to me. Not really a difference between “What are you doing” and What’s Happening” I think maybe less words in your catch phrase makes it more appealing?
