Attached are the two charts that I've come up with so far (in collaboration with Ellen Conant who is working with Bridge Foundry, helping to articulate strategy and refine our messaging). These illustrate how the number of workshops have grown over time -- we might still be missing one or two, but I think the data is good for showing the incredible work of the volunteers in organizing a huge number of workshops, and start to tell the story of the impact beyond the specific events.
The first has editorial annotations of how RailsBridge influenced many other groups -- I may be missing some, but these are ones where I have first hand knowledge or they have written stuff that acknowledge how they were inspired by or forked our early work to create their org/event.
The second shows how the growth has continued -- with the "refactoring" of the org, other leaders wanted to join us and work together to share information and resources, while innovating on specific tacts.
We're experimenting with alternate visualizations to tell the story. I wanted to share this work-in-progress, and it would be great to hear your feedback and ideas.
