The length of the messages we send on Twitter is getting shorter, raising important questions about how the social messaging service is changing the way we communicate, say researchers. Back in the old days, say in 2009, Twitter was a relatively unknown social network that was beginnign to spread like wildfire. In 2007, Twitter users posted some 400,000 tweets per quarter, by June 2010, they were posting 65 million each day. Today, there are 200 million registered users who send around 400 million tweets every day.
