A reverse blog is a type of blog that is characterized by the lack of a single, specific blogger. In a traditional blog a blogger will write his or her comments about a given topic and other users may view and sometimes comment on the bloggers work. A reverse blog is written entirely by the users, who are given a topic.
A reverse blog is characterized primarily by the lack of a blogger on a site providing blog-style content. The number of comments must be limited in order to differentiate a reverse blog from a forum. This number of comments must be fixed as well. These are the primary and necessary characteristics of a reverse blog. The reverse blog is also commonly called an inverse blog.

The Reverse Blog has gained popularity over the years as users have developed a disdain for traditional blogging. In general, users are not willing to monitor the comments of one blogger. Instead, they would prefer to make a blog themselves. In order to deal with the increasing number of unread blogs, reverse blogs were created. These focus users into a common area to represent various topics and (optionally) rate each other's content.
