Have you visited the Internet Archive lately?  It's officially (as of this month) a library.  Coming soon: a tool that will make it really easy to upload videos and mark them with tags.  Now, you've heard of this already -- there are several commercial applications that do this.  But the Internet Archive is dedicated to archiving and preserving web content:

The Internet Archive is working to prevent the Internet - a new medium with major historical significance - and other "born-digital" materials from disappearing into the past. Collaborating with institutions including the Library of Congress and the Smithsonian, we are working to preserve a record for generations to come.

I visited the Internet Archive building in San Francisco today.  It looks as if the Internet Archive and OneWebDay will be collaborating, and I couldn't be happier about that.

One project that needs doing, and needs leadership and prodding:  interviews with people about their early web involvement and memories.  The Archive has a nice Computers and Technology video area, but a much more substantial project would be to have citizen journalists out there recording interviews and making the raw footage available to everyone via the Archive.  This may be a OneWebDay project in the making -- if you'd like to volunteer to work on this, the barriers to entry are vanishingly low.
