One of the coolest features of geni are the "Projects". Projects are a great way to collaborate and gather together in one place profiles of people that share something in common.
I'd love to see spotlighted in this thread some of the projects that you've run across that you think others would want to know about, why you like them, and what you find interesting about them. Feel free to even brag about a project you've started that you feel that others would find of interest.
If you don't know much about geni projects check them out here http://www.geni.com/projects
The project with the most recent changes will always be at the top of the list and with over 7,000 current projects you'll find the search window an absolute must.
Geni also did a webinar on collaborative genealogy and "projects" are an important part of that. You can watch the video on youtube here:
