Post It Notes

Does anyone use Post-It Notes (sometimes yellow, pink, or blue sticky notes) on their monitor or the shelf the monitor is sitting on?

I stick PostIt notes all over now. What I realized is that

It is time consuming and frustrating to look up a web site or a help document, just to access some information that should be readily available on a post-it note.
A binder/large sheets of paper take up desktop space, and like the above, are time consuming and frustrating in some cases versus a post-it note.
Back up important post-it notes in a binder with paper in it. If someone ever steals your post-it note or you vacuum it up, at least you have a penciled back up in a binder, or somewhere safe.
Use pencil and erasers on post-it notes so that you can change and update them as necessary
write small on the post-it note.
get different sizes of post-it notes, if you find you are cramped for space
It is good to have a the computer monitor on a shelf on your desk, so you can use more post-it notes on the shelf, in addition to on the monitor itself.
if all the post-it notes get messy looking, you could try different colors which look better in the surroundings
commands that you need to memorize, or small code snippets that you just can't remember, but use often, are good on post it notes.
Post-it note software is silly, because I've had all my post-it notes corrupted a few times. The computer has to be on (you may have some bios setting that you need on a post-it note, or something to remember during bootup. So it's better on a real post-it note, versus software)
If a post-it note has been re-used and erased many times, consider throwing it out and starting a fresh post-it note.
