if people want to waste time they don't need the internet to do it. when people don't get their work done it shows. The good part about people goofing off on the net is, thier still at their desk, so you dont have to go looking under bathroom stall doors to find them, wasting your time as well.
the people i work with do not waste too much time on the net, and we do most of our work on the internet so it would be easy enough to do. IMO most people have a good work ethic and the internet dosn't change that. it allows us to get more done with less effort.
