Computer Addiction

Why is it that drug addicts and computer aficionados are both called users?

Super Fast Computer has a little tid bit on online addiction. I know the feeling as I find myself sometimes just sucked into the computer. As part of my former addiction I'll post a few screenshots showing you all my alter-life. If anyone knows of some good links for self-help groups let me know. Not that I (cough voice lowers) need them, strictly research you know.
