Stands for Nerd Attention Deficiency Disorder. See if you have it:

The presence of NADD in your life is directly related to how you’ve dealt with the media deluge of the new millennium. You’ve likely gone one of three ways:

1) You’ve checked out… you don’t own a TV and it’s unlikely you’re even reading this column.

2) You enjoy your media/content in moderation. When I asked you to count how many windows were open on your desktop you either said, “One, my browser for which to read this article” or you made yourself a note to yourself to check this AFTER completing this column. In a previous age, you were the type of person who kept their pencils very sharpened.

3) You enjoy the content fire hose. Give me tabbed browsing, tabbed instant messaging, music all the time, and TIVO TIVO TIVO. Welcome to NADD.

The presence of NADD in your friends is equally detectable. Here’s a simple test. Ask to sit down at THEIR computer and start mucking with stuff on their desktop. Move an icon here… adjust a window size there. If your friend calmly watches as you tinker away, they’re probably NADD-free, for now. However, if your friend is anxiously rubbing their forehead and/or climbing out of their skin when you move that icon 12 PIXELS TO THE RIGHT, there’s NADD in the house. BACK AWAY FROM THE COMPUTER.
