Abstract:

OOo Writer scores most of its victories in features that make the creation and maintenance of highly formatted or long documents easier. This pattern is not accidental. According to Elizabeth Mathias of Sun Microsystems, the documentation of OpenOffice.org has a long history of being written in Writer itself. As a result, the program's developers had the incentive to include the tools they needed. This legacy continues to give Writer advantages over competitors like Word.
