Twitter BOSS: Tweet too much is unhealthy

It's enough to make any PR agent wince. The co-founder of Twitter has urged its 500million users to get off the micro-blogging website and do something else instead.

Christopher Stone said he did not want anybody to spend hours using the site because it is ‘unhealthy’. Instead he said they should dip in and find what they want – then stop and do other things.

Mr Stone was one of the four men who created Twitter in 2006 and has remained creative director, helping it become one of the most influential social networks in the world.

But users have repeatedly complained that it is incredibly addictive, with some staying logged on for 12 hours at a time. At a conference in Montreal, Mr Stone, 37, said using Twitter that much was not what he intended. ‘To me, that sounds unhealthy,’ he said.
