I signed up for Twitter several years ago but struggled to understand the point. What is it? What is it for? What information can I share in 140 characters? I did what millions of other people do: followed famous people, sportsmen, rappers, comedians and actors. Much of the time, it turned out, they didn't have anything that interesting to say and, after a few weeks, I gave up on it.
Then, as the site grew in popularity, I decided to give it another chance. I had about 30 followers, mostly my friends. Every few days I would tweet about what I was doing and share songs, music videos and news articles and now and again I would tweet one of the many musicians I followed. Good fun but not particularly productive.
