A weblog (blog) is a website that contains a log or diary of information, specific topics or opinions. A blog author (blogger) links to stories or other websites with relevant and interesting information. These links are typically segregated according to the blog's topic or subtopic and written in reverse chronological order, meaning that the most current links display at the top of the blog's home page. Another major characteristic of blogs is the ease of use to post. Prior to blogs, you needed to understand HTML to produce a website or otherwise involve a back-end production team. Blogs opened up online publishing to the masses.
