The term "Blog" is short for weblog. A blog is a post that is written from the perspective of an individual or group. The spectrum of blogs and bloggers is staggering -- encompassing just about every topic imaginable. Likewise, the spectrum of blog writing styles varies widely from the very personal to the very professional. Blogs are almost always first-person and their insider-perspective often makes them a credible and engaging source of information. Blogs are social media in the sense that readers can contribute to the blog via comments. Additionally, a blogger may have a rich network of readers with whom he or she has credibility and influence.
