The FrameMaker eco system
Adobe InDesign, Illustrator, and other mainstream layout and DTP applications have a vast ecosystem. There are literally millions of premade InDesign templates, Illustrator stock drawings, etc., to be found in the extensive stock databases. This is not the case for users of Adobe FrameMaker, RoboHelp, and Captivate. Users of the Adobe TechComm products have a rather small selection of service providers to choose from and an even smaller selection of add-ons like scripts and stock content. The lack of creative content is likely a significant hindrance to attracting new users.
