Introduction
Nowadays, security must be taken very very seriously. And when I'm talking about security, I mean the security of your data. As a user, I work in Linux for the majority of my time (the rest is when I don't play games and that's when I have to boot into Windows, but that's pretty rare anyway...). So, all my personal files are under my profile directory, under /home. If you work with a laptop or netbook or other mobile computer, then it's imperative that you encrypt your files just in case you become a victim of theft. In this case, you'll be sure that at least your files won't be exposed to the thieve's eyes.
