If that is really the case, maybe a beginner session for the first time slot each year should be a very basic overview of technology buzzwords and concepts rather than having so many speakers repeatedly explaining the same basic processes. Or have a “things you should know before attending RootsTech” cheat sheet available in advance to bring everyone up to speed on the very basics of the topics to be presented.
Two of RootsTech’s biggest strengths are promoting the spirit of collaboration between vendors and introducing innovative ideas that will make the future of genealogy brighter. Those things alone make it a worthwhile conference. If you have an opportunity to go, you should take it.
