What is a blog primarily defined as?

A blog is primarily defined as a web log that contains personal comments and observations. This format allows individuals to express their thoughts, share experiences, and provide insights on various topics in a more casual and interactive manner. Blogs often reflect the author's personality and are updated regularly, creating a space for discussion and engagement with readers.

While blogs can serve multiple purposes—including marketing or being part of professional communication—what distinguishes them is their informal nature and the personal touch that writers inject into their posts. This contrasts with formal business reports, which adhere to structured formats and objective language, and newsletters, which are typically more focused on conveying information to a specific audience without the personal angle. Although businesses may use blogs as marketing tools, the essence of a blog remains rooted in personal expression and commentary, making it distinct from other professional and business communication methods.
