I still miss my Aureal soundcard. I remember being able to pinpoint where people were in Counterstrike by sound. I have a Steel Series set now and they definitely aren't pinpoint.
Just about every sysadmin I worked with thought in /24s. A lot of people are used to deploying the Linksys home routers and can't think about subnets or supernets. It used to blow peoples minds when they would get a .0 or .255 address because I had them on a /22 or /23. Even the last network engineer I replaced had multiple /24s all over the place across our WAN. I couldn't summarize routes because he didn't use sequential subnets, just random ones all over the place. Drove me nuts.
