It’s the Electronic Frontier Foundation’s annual Power Up! week, when donations to the charity are matched by a group of challenge donors, making every tax-deductible dollar you give count twice! I’m a contractor for EFF (my fees come out of a grant from the MIT Media Lab, where I’m a Research Associate), and I’ve been involved with the org for more than 15 years now, and I’ve never seen a nonprofit spend its money smarter to make more of a difference in the world.
