Twitter turns five
Happy 5th birthday Twitter.
I could be wrong but I very much doubt that when Jack Dorsey posted that very first tweet that he imagined there would be a billion tweets a week just five years later.
That's impressive growth no matter how you look at it.
When it launched Twitter employed 8 people. Now it around 400.
For me though one big question remains unanswered - how on earth they make enough money to pay those 400 hundred people?
