Twitter co-founder Christopher Isaac (Biz) Stone has a message for those followers who stare at their tweet feed for hours on end.
It's not healthy.
Stone says he'd prefer that people visit the popular social networking site frequently than sacrifice their life to it.
He told a Montreal business audience even he is amazed by the influence of Twitter, which the founders initially thought would just be used for fun.
Stone says it has instead ended up linking millions of people and been used to spur social change such as the so-called Arab spring, triggered by pro-democracy movements in the Middle East.
The entrepreneur's speech focused on tips for business people including that they should show empathy for their employees and shouldn't be afraid to fail.
He also says creativity is an unendingly renewable resource.
