Unlike its main competitor Delicious, Ma.gnolia stored snapshots of bookmarked web pages. The browser displays a thumbnail image of each bookmarked site. At each event, websites were bookmarked, books, journals and videos selected from the archive. Pages can be bookmarked for reference, and notes can be added to relevant content. Folders and catalogs can be bookmarked, and comments can be added to images. The images bookmarked by a user are available for any user to view. Bradley expressed his belief that "some of these items might have been bookmarked". Sections of code can be bookmarked for easy reference. Planning units can be interrupted and bookmarked so they can be resumed later. With the PRG pattern, the URI of the request can safely be bookmarked.
