At one point in my career, I trained business analysts in the tools and techniques of their trade. One feature of business analysis methodologies is that they use a lot of diagrams to visually represent use cases, process flows, and relationships. During those classes I talked a lot about creating and sending diagrams to others, but I never dreamed that we'd be able to collaborate on them from just about any device. That's what the LucidChart HTML5 web app brings to the picture -- amazing diagramming tools and online collaboration.
