A blog, short for weblog or web-log, is an online publication format. The blog author publishes articles – often referred to as “posts” – on a regular schedule.
Blogs, and the accompanying blog-publishing tools and software, span a wide range of topics and uses, from personal diaries to corporate publications, information and resource sites, and more. This glossary and Ask Leo!itself are published using blogging software.
In its most common form, a blog is simply characterized by a single website (or area of a website) containing a series of articles presented most recent first.
