One solution that comes to mind would be to add an option to the bottom of the "Create New Document" menu called "Create New Template". Here, the user could choose from a list of document types such as "LibreOffice Presentation", "LibreOffice Spreadsheet", etc. I'm not sure how the available template type would be exposed by the applications to the menu.
Once the user selects one option, a dialog could appear and ask them to name their new document, after when Nautilus could open the ~/Templates folder with the newly created and named template within. In this way, the user would figure out how the templates system was supposed to work without having to visit a website or ask someone. Perhaps the name dialog could also offer some sort of brief explanation of what happens next.
