Attached is my slides and the one VIM I demonstrated for the What's New in 2017, and 3 Reasons to not use NXG and three reasons to use it.
The rest of the WebVI material shown cannot be shared as source since NXG 2.0 is still in beta but I've uploaded the two demo outputs from it which can be ran in Firefox without anything else. My sites links will be up for now, which are referenced in the slides.
