Here are two "Best of the Best" Guides from the Springshare Community that offer useful advice and good tips on LG design.
Working Inside the Box: LibGuide Tips for Librarians @ Agnes Scott College (GA). This web site echoes many of the same ideas and tips in "Liberating Libguides." The Home Page starts with how to "write for the web." The author also suggests a number of supporting software tools to help build more visually engaging guides with dynamic content including image capture and editing tools, RSS feeds, and creating widgets. There is also a tab for customizing LG for mobile users.
Libguide: Quickstart Help & Standards @ the University of Regina (Canada). This guide is dense with step-by-step detail but useful to someone new to the platform or needing a refresher.
