How are blogs different from standalone documents and webpages?

  - Potential public nature of posts, and, if comments are enabled, readers can post responses and the author can reply.

  - Narratives and traditional documents are sequential mediums; blogs are not, so all posts must function coherently as standalone texts, because users might not access any specific order or subset of posts or even visit the main blog.

  - Essentially an automated database, with each post a separate database item, blog software can be used to store, sort, categorise and retrieve posts (eg. by date, chronological order or by category or meta-tags). Database functions are handled without users needing to understand or work on databases. Posts contain text formatting and media embedding without users needing to use or understand HTML directly. Unlike conventional documents/hierarchical storage, posts can be in many categories simultaneously.
