Thoughts on a Personal CMS

I'm accumulating a lot of documents (from the web, from scanned bills,
from digital pictures, etc). I'd like a convenient way to manage and
access these, including:

Presenting attractive "albums" of pix,
Searching and accessing my bookmarks,
Searching and accessing scanned documents,
Low level of admin attention,
Some measure of security.

There are things like Blogs (hence this site), Zope/Plone,
MoinMoin/Wikis and hand-rolled systems.

But they all fall down in one way or another, either not presenting
attractively, requiring too much work, low security, etc.

Still thinking.
