Kudos to Alex Bosworth for figuring out a clever way to save bookmarks semi-privately in del.icio.us. It took me a moment to sort out how this works because it depends on a feature I didn’t know del.icio.us had: the ability to tag an item for a friend. I could find no documentation on this, but eventually guessed correctly that if I want to tag this page for Stephen O’Grady, I can use the tag for:sogrady. Now it’s listed at del.icio.us/for/sogrady, but only Stephen can view that page.
Just wanted to add: If someone out there who likes to have Del.icio.us in his weblog, just ask.
