@ryanmrichard, you seem to be using a number of tinyurl links in the article. Is there a particular reason for that? I would generally prefer to expose the full direct link instead of a shortened reference. It allows readers to use the hover preview of the link to get useful information and decide whether they want to follow it or not. It is generally considered more friendly from a cybersecurity standpoint too.

Unless there's a strong reason, I'm going to replace the tinyurls with their expansions. Please let me know ASAP. Thanks

@bernhold I used the tinyurl links as a force of habit. In my other projects I'm obsessive about not going over 80 characters per line and markdown doesn't have a great way for splitting long URLs (at least that I've found). I think your changes look good!
