LOL , please don't teach people that kind of thing.

Well, it's true that  you can pull off a device when nothing is 
accessing it. it's the same thing on windows too. But how are you sure 
nothing is accessing it ?

The advantage of Linux is that there is not much processes running on 
background that will access your stick without letting you know.

So the very thing to do is to unmount your disk to be sure that nothing 
will access it when you'll unplug it. gnome and kde offer a User 
friendly way to do it by right-clicking. but on the Shell :

$ sudo umount /media/<my usb stick>

should do it too .
If it doesn't want to unmount the you can add the -l flag.

$ sudo umount -l /media/<usb stick>

anyhow, never pull off your stick or disk without unmounting it.
