Now, a blog is a term that’s often thrown around, but it originally came from “web log.” It’s like an online diary that is powered by a typically easy to use content management system or software such as Blogger.com or WordPress.com, and it can be updated frequently and easily without requiring any HTML or web publishing skills. Now, popular blog publishers invite their visitors to comment and share opinions on the relevant topics they’re speaking of. So, the point of a blog is to dialogue with your visitors so that they, in turn, can help deliver and create content for you, and you build a community that way.
