My comments in response to Maintaining Your Digital Presence Is More Than Updating Your Status
This is an important topic and well suited to the Smithsonian :-) Many people don't realize how ephemeral are digital media is. It is much easier to view photos from the 1970s than images from the 1990s (that are probably locked on some hard drive or floppy disk or zip disk [remember those].
Web sites close down and go out of business. Trusting them with your history is unwise. Sharing it there is fine but you can't rely it will be their for your kids. The internet archive (wayback machine) is pretty awesome and seems likely to survive but...
Dealing with electronic records is obviously going to be a big job for places like the Smithsonian going forward.

To some extent I think they maintain more copies of popular sites, but even so most of my sites have several captures a year) - Curiouscat.com backups on the wayback machine from 1997 to today
