Because this subject was previously mentioned on Foundation-l and Research-l, I thought that those who are interested in research budgets might want to look at the information that’s now available here. Thanks to Steven Walling (WMF) for following up. I’m hoping that we’ll see more of this kind of information in the future so that the community can compare ROIs of proposed and completed projects.
