There is a basic flaw in the survey. It says 12.5% or 1 hour is lost which translates to 8 hour work day. When was the last time a working professional was able to do an 8 hour shift. Everyone is spending about 10 to 12 hours at work place which is completely ignored. The fact that there is no overtime but still people work beyond working hours is not considered in the so called productivity.
Also most of the firms have blocked the sites and it is not possible to access then anyway. We should not read too much into this survey.
