Spending hours on twitter is unhealthy, says Twitter's creative director.
Biz Stone, who is also the creative director the micro-blogging site, said users should visit the site for information but leave once they had found it.
Speaking at a business conference in Montreal, Canada, Stone said that using Twitter for hours at a time "sounds unhealthy".
"I think that's a much healthier engagement. Obviously, we want you to come frequently," he stated.
As reported by Montreal Gazette, the social networking guru also said there were no plans to increase Twitter's 140-character limit.
