The document discusses the history and uses of blogging. It notes that before blogs, people communicated online through message boards and early social networks. A blog is a website with regular commentary or posts by an individual or group. Blogs can be on any topic from personal journals to reviews. Blogging is now used in classrooms for students to share work, get feedback, and help each other learn.
