The good news for me is that everyone wants internet freedom at work, in fact almost every time I walk by one girls office she is on perez hilton, or popsugar, etc. so I think I'm safe for awhile. As for them monitoring, I'm friends with the tech guy, so he would warn me first. I actually still manage to get work done.
I'm with the ladies that check it more at work than at home. Actually my purse obsession started at work when I had nothing to do and started thinking of a way to spend my bonus. A search on google turned up some sites, I checked out TPF and the rest is history.
