What is business blogging? First we need to define what a blog is. Wikipedia and Blogger.com define blog as a website where entries are made in journal style and displayed in a reverse chronological order.
Blogs often provide commentary or news on a particular subject, such as food, politics, or local news; some function as more personal online diaries. A typical blog combines text, images, and links to other blogs, web pages, and other media related to its topic. The ability for readers to leave comments in an interactive format is an important part of many blogs. Most blogs are primarily textual although some focus on photographs (photoblog), videos (vlog), or audio (podcasting), and are part of a wider network of social media.
The term "blog" is derived from "Web log." "Blog" can also be used as a verb, meaning to maintain or add content to a blog.
