I am a graduate student at the University of Illinois at Urbana-Champaign. I am doing a study soon on the effects of CVS and mail visualization on open source communities. Check out my work here:

If you are a developer, I could use your help. Look at the visualization, do some surveys and we give you a $20 gift certificate to newegg.com.
I am not ready quite yet; still waiting on IRB approval (http://www.irb.uiuc.edu/). Please keep us in mind if you are interested... I will ask again soon, and then that's all the spam. Contact me if you want more information now.
