Blogs are usually (but not always) written by one person and are updated pretty regularly. Blogs are often written on a particular topic - there are blogs on virtually any topic you can think of. From photography, to spirituality, to recipes, to personal diaries to hobbies - blogging has as many applications and varieties as you can imagine. Whole blog communities have sprung up around some of these topics putting people into contact with each other in relationships where they can learn, share ideas, make friends with and even do business with people with similar interests from around the world.

A blog is basically a journal that is available on the web. The activity of updating a blog is "blogging" and someone who keeps a blog is a "blogger." Blogs are typically updated daily using software that allows people with little or no technical background to update and maintain the blog.

Blogs usually have a few features that are useful to know about if you want to get the most out of them as a reader. Lets examine a couple briefly.

Archives - You might look at the front page of a blog and think that there is not much to them. A few recent entries, some links to other sites and not much else. However its worth knowing that there is a lot more going on under the surface that might initially meet the eye.

When a post is first written it goes to the top of the front page. As it gets older it begins its journey down the page until it disappears from it. This is not the end of its life however, because it goes into the ‘Archives’ of a blog. It sounds like a dusty dark place but its really just like a filing cabinet that is easily accessible in a couple of ways. You can read the ‘archives’ simply by looking on the ’sidebar’ on the left or right at the ‘archives’ or ‘categories’ section. There you will see links to all the old posts which you can access either by category. You’ll see a category for ‘Advertising’ - click that link and you’ll see all the old posts on the topic of Advertising with the most recent at the top and the oldest at the bottom.

Comments - Not all blogs use comments - but most do. You can give feedback on almost everything that is written simply by clicking the ‘comments’ link at the bottom of each one of the posts. This will take you to a little form where you leave your name, email and a link to your own blog if you have one as well as your feedback, comment, critique, question, essay on why you love the blog, promise of money…. etc).

A great way to learn about blogs is to read a few. Leave some comments, ask questions and bookmark your favourites. An even better way to learn about blogs is to start your own.

In conclusion a blog is an easily, instantly, and frequently updated Web site, focused around a topic, industry, or personality and is an easy way to earn money online.
