I think people screw around for a fraction of the day, as a break from coding all day. It might make you more efficient overall. A bit like HIIT training for 10

I think people screw around for a fraction of the day, as a break from coding all day. It might make you more efficient overall. A bit like HIIT training for 10km vs. sprinting 10km. Also if the work is getting done its probably OK. When you buy that $10/month plan from Netflix, do you want to know that someone was working hard (not slacking) for 10 minutes at $60/hr ... or do you want to reliably watch movies?
