Always Up-to-Date Glossary

This is a tricky subject. It’s great to be able to sit down and read a blog about a particular topic and not have to have a dictionary by the side. At the same time, it can be really hard to discuss things without becoming too wonky. As the number of posts has grown, it has become a bit evident that a glossary of more common terms is probably a good addition to the site. Though the discussions are aimed to be understood by anyone, there’s no escaping the various nuances of laws, regulations, and technical jargon that might indeed be alien or look like a collection of alphabet soup. This is where that soup gets condensed into its bare essence. This will be divided into two sections: acronyms and terms. The division is perhaps not necessary, but does smooth things out a little.
