How often have we looked at our own sites from a users' perspective! Probably not often enough.
I make a point of looking at my site on other people's machines whenever I have the opportunity. I never know what weird settings or software that they may have that I hadn't thought about accomodating.
Back to the original topic I have known of novice webmasters who have managed to block their own IP address!
