Esri has released a really informative Story Map promoting the use of its next generation hillshade layer. The map provides a great introduction to Esri's multi-directional hillshade layer (available in ArcGIS Online, ArcGIS for Desktop and web apps created with an ArcGIS Online organizational account). It is also a great general introduction to the art of hillshading and how hillshade layers can enhance your maps.
A Hillshade Everyone Can Use compares the new multi-directional hillshading to traditional hillshading (swipe left & right on the map to compare old with new). It also provides some great examples of how a hillshade layer can provide a clearer context to topographical map features and other mapped data. In particular there is a great example map showing how a hillshade layer reveals some of the effects the landscape can have on wind turbine placement.
