Mihai Parparita from Google has written a(nother) cool script that allows you to add the bookmarks from del.ico.us to Google Bookmarks. The live version is available on his site.
Unlike del.icio.us, Google Bookmarks keeps your favorite web pages private and lets you search their content. You can manage your bookmarks from the site, using Google Toolbar for IE or using some unofficial Firefox extensions.
