Twitter, YouTube actually make workers ... more productive?

Study author Brent Coker, from the University of Melbourne said ‘workplace internet leisure browsing,’ or WILB, helped to sharpen workers’ concentration.

‘People need to zone out for a bit to get back their concentration,’ he said.

‘Short and unobtrusive breaks, such as a quick surf of the internet, enables the mind to rest itself, leading to a higher total net concentration for a days’ work, and as a result, increased productivity.’
