Are your scrapbooks readily accessible? Are people afraid to touch them b/c they are "artsy"? Our scrapbooks get looked at ALL the time, it's DDs favorite thing to do whenever they start missing Disney.
the other thing I've done is to make a calendar with our favorite pictures, so each month we get a fresh look. There are blank 12x12 and 8x8s available for that. I like the 12x12 /c at the end of the year, I can just put it in an album and it's pre-scrapped.
I've also done pages that I put in a 12x12 shadow box frame, so I can display, then rotate them into the scrapbook.
I would NEVER depend on digital preservation. It has it's place, but sitting down, turning the page and reading the hand-written word is SO important.
