Anyone can learn to start a WordPress blog. There are two different types of WordPress blogs that you should know about.
One is the basic free blog that you can start by typing in your email and inserting your username and password. You create a new blog and if the domain is available you can have your own. Since you are using WordPress your domain will have the WordPress extension. For example if I was starting a blog about home improvement, the end of my domain would have WordPress dot com. The drawback to using the free service is that there are so many limitations. For one you can only use the themes that they provide for you to use. Also you cannot customize your site the way you want to, at least not for free.
The second kind of WordPress blog that you can create is called a self hosted weblog. These are the most popular amongst true bloggers because you can have total control of your site. Basically what you do is install WordPress onto your own hosting. If you have never done this before you may want to take some training.
I must tell you that this is totally worth your time because once you know the process you can create as many blogs as you want on one hosting account. This is the beauty of having a self hosted weblog. Once you have your blog installed you can start to promote your blog and gain a huge readership. Who knows, maybe a company would want to advertise on your start bring in some revenue for you to keep
