When you sign up for a website with us, you will have the ability to post blogs to it (if you want to). We don't provide blog posts, we simply give you the ability to blog on your website. If you don't want to blog, we will simply turn the blog off so you won't have an empty blog. Blogging is a great thing to do, but it is not required.
These blog posts you are currently seeing are just placeholders so you can see how the blog works with the website.
