Twenty, all in a single menu (I have set up no submenus), and all with a single word name in order that I can easily type it to use with a shell script that I use to launch the browser with loading a bookmark (the shell script uses SQLite to make a list of bookmarks if no name is given, as well as using SQLite to find the URL of the bookmark if the name is given). Occasionally I delete some, and occasionally I add some. I don't use the bookmark toolbar.
