Have you tried WhatIs.com's Word of the Day e-Newsletter? It's absolutely fantastic. Every day it sends you the explanation of 1 information technology term, along with links to articles, trivia, and so on.
That's the first e-mail in my Inbox which I open and read every morning. Five fun minutes to a sharper intellect.
Today I learnt what a Slingbox is. Yesterday I explored Holographic Versatile Disks (HVD). Every day there is something new to learn.
