To begin, let’s see what blogging and blog is in general.
“Blog” is an abbreviated version of “weblog,” that is a term used to describe websites that maintain an ongoing chronicle of information. A blog has diary-type commentary and links to articles on other websites, usually presented as a list of entries in reverse chronological order. Blogs can be personal and political, and can focus on one narrow subject or a whole range of subjects.
Many blogs are focused on a particular topic, such as web design, home staging, sports, or mobile technology. Others are more eclectic, presenting links to all types of other sites. And there are also blogs that are more like personal journals, presenting the author’s daily life and thoughts.
In general, blogs tend to have a few things in common:
- A main content area with articles listed chronologically, newest on top. Often, the articles are organized into categories.
- An archive of older articles.
- A way for people to leave comments about the articles.
- A list of links to other related sites, sometimes called a “blogroll”.
- One or more “feeds” like RSS, Atom or RDF files.
A blogger is the owner and runner of a blog or a person who maintains the blog. That means, posting articles or new posts, information, sharing the most up-to-date news, opinions and case studies to name but a few. And such kind of entries are known as blog posts.
The content on a blog, consists of articles that the author(s) writes. Some blogs have multiple authors, each writing his/her own articles. Normally, blog authors compose their articles in a web-based interface, built into the blogging system itself. Some blogging systems support the ability to use stand-alone “weblog client” software, that allows authors to write articles offline and upload them at a later time.
Most blogs allow visitors to leave comments. There are also nifty ways for authors of other blogs to leave comments not even visiting the blog. “Pingbacks” or “trackbacks” can inform other bloggers whenever they cite an article from another site in their own articles. All this ensures that online conversations may be maintained painlessly among various site users and websites.
Blog is also a nice way to keep track of articles on a site. A lot of blogs have an archive based on dates. The front page of a blog may have a calendar of dates linked to daily archives. Archives can also be based on categories with all the articles related to a specific category.
You can also archive your posts by author or alphabetically. The ability to organize and present articles in a composed fashion is much of what makes blogging a popular personal publishing tool.
