I'm at work. I do a bunch of coding on my project(s) for an hour or two, then check in here for a mental break. Since I don't smoke or drink coffee, I consider it the equal of others taking a smoke or coffee break.
The owner of the company and I (when I wear my VP IS/IT hat) set the policies regarding internet usage. We have a very easy, liberal policy - as long as it's not illegal or bad for the company or customers, it's acceptable. We have hard working employees who work long hours so internet access is pretty much a "perk". We use it
A LOT for software development support, VPN access with a couple of business partners, downloads, research, etc. so any "cyber police" attempts would ultimately be a big headache.
Worse case, I can always argue that I am testing our internet connection, firewall, etc.!!!
