Here's another way to exploit Fatty.

Assuming you have it working and your mod rewrite/htaccess working correctly, you now have a site that you can link to "at will".

As you set up a blog network, you can link practically anything to your Fatty.

For example, you make a blog post, choose a few keywords in your post and use them as anchor text/ links to your Fatty. You don't need to create a content page, you know Fatty will do this for you:

In the late 60's, Elvis made a comeback in Las Vegas at the International hotel and casino.

I didn't have to bother creating any content pages, Fatty will do it for me. Not only am I creating links "on the fly" to my Fatty domain, I'm also offering more content and resources for my blog readers.
