Relational networks can be as linear as you want them to be. Some presenters keep most of their content in standard linear shows, and then do three things:

• They link all of these slide shows together via a switchboard.
  
• They integrate internal navigation within the linear shows so that individual slides are randomly accessible if desired.
  
• They attach a Resources section (accessible from every slide in every show) that contains supporting materials arranged in categories.

With this organizational strategy, content can be delivered either in traditional linear style or as randomly as desired.
