Basics
A blog is the short name for the original meaning “weblog”. A weblog is where posts or articles from a person or many people are displayed in date order. “Blog” can also be a action or a verb that means do post to a blog or update a blog
Many blogs blog about a certain topic, meaning they post articles every now and then or mostly daily about a certain topic or subject, this is also called niche blogging . On the other hand other people use blogs as something personal, where they blog about personal things and share it with friends or the world on their blogs.
Normally a blog exists out of text, images, links, videos and the normal articles and blog posts. But one of the most important parts of a blog is the comments. Blogging and comments goes together, if you have a blog without comments you probably have a website only and not a blog. A blog should be interactive.
You also get micro blogging which has really lifted off in the past year. Technorati tracks already more than 113 000 000 blogs worldwide.
Cms
Most people still use Wordpress to blog, Wordpress is still considered as the leading open source blogging platform for many. Althouth with the release of Drupal 6 some people have turned there but Wordpress still rules as the blogging cms platform
Money
Many people have gotten a name in the blogging industry or blogging world and now live of their blogs. This has caused a explosion in the Make money niche.
The make money niche is niche blogs that blog about the “make money online” niche. While most of these bloggers make a quick buck or two the most of them still cant live from their blogs.
Competition
A few years ago big corporate companies could easily whip out a small blog and he could not be found. But blogging has become more famous than almost any other publishing platform and more people read blogs today than people that read newspapers and news on the tv.
The competition in blogging for a living is huge.
