The word blog is short for "web log". It's an easy and convenient way for you and I to publish content to the internet. It's also an easy way for other people to read the content you and I write. In fact, if you write a good blog (good, useful, interesting information), you'll get people returning often to your blog to read what you write. The more visitors you get, the more money you'll make. Write a good, useful, informational blog. You'll make money.
