This document is an introductory course on creating and managing posts and pages in WordPress. It introduces posts as content that is timely, organized by categories and tags, allows user comments, and includes author and date. Pages are described as "one-off" content that is timeless, not meant for interactivity, and hierarchical with subpages. The key differences between posts and pages are outlined as posts being timely, social, and included in RSS feeds, while pages are timeless, not social, and hierarchically organized without authors or dates. The conclusion prompts self-reflection on using posts versus pages for different types of content.
