Spending hours tweeting is unhealthy: Twitter boss

Don't spend hours tweeting, it's "unhealthy"— that's the message from Twitter's boss. Biz Stone, co-founder and creative director of Twitter, has told the popular micro-blogging site's 500 million users that spending hours tweeting is not healthy.

He says he'd prefer that people visit the popular social networking site frequently than sacrifice their life to it. Instead fans should use the site to find what they want — and they go and do something else, The Daily Telegraph online quoted Stone as telling a conference in Montreal. Users have complained that the 140-character messaging site is addictive, with some staying logged on for up to 12 hours at a time.
