I only open it to look for big files I don't need or see where my space is going. It's not something you keep open all the time.
Also, I believe Private is where the Sleepimage is kept. I have mine disabled so my Private is only 2GB. Yours is 6, so I assume you have 4GB RAM? Am I correct?
Is DaisyDisk showing file sizes in the old style or the Snow Leopard style?
Also, in GrandPerspective, you can turn on "Show unused space" in the drawer. It should show black for empty space and grey for "miscellaneous" stuff the system needs.
