Rands has an interesting blog and has made a couple of posts on what he calls Nerd Attention Deficiency Disorder or N.A.D.D. Read the first post and then the second post. It is quite interesting.

I have N.A.D.D. and I think most geeks do, or need to, in order to be productive. It’s just what we do. I need to be have several different windows/applications open on my computer or else I don’t feel like I’m accomplishing much. When is it too much though?
