1. Metanotational typefaces (FontAwesome to AlphaSymbolic — Blissymbols anyone?)
2. Perspective-based grid systems (Grid systems to build basic interactive Webworlds, instead of Websites)
3. Modular CSS Architecture (Using Grunt to compile CSS that lives with JS Modules, served on demand via RequireJS; a more meaningful folder architecture other than the dreaded "css" folder at project root[0]; I namespace my CSS/LESS/SASS as I namespace my Business Objects or Entities, and I namespace my CSS/LESS/SASS by module/state/verb.)
3.1 Modern Web DRY (Best way to package and create shareable front-end code?)
4. UI Semantics for Accessibility (What else can we add as sibling to "Skip to Content"? — It really is an Accessibility Hook within a list. What about Accessibility Hooks everywhere?)
5. Responsive/Adaptive Images by Cool URL[1] (Responsiveness as a Service?)

you shouldn't avoid a glossary. and put in jQuery there as well, it is a vital component. it wont hurt to touch on responsive design across different devices. simplify that and you got a winner.
