When Twitter was first launched back in 2006, many of us were sceptical about whether it would last. What was the point of a tool that only let you send 140-character updates? Why not use Facebook which has a status function plus much more?
Many social journalists never expected it to hit the 5 million mark of users, let alone 500 million. But almost overnight Twitter became an online phenomenon. Today, over 340 million tweets are sent daily from teenagers, worldwide celebrities, small businesses and the largest conglomerates.
