There are so many awesome projects, but one that I recently learned about is GNU Taler. Basically it's an attempt to make "socially responsible digital cash", where all customers' transactions are private (you cannot tell who bought what or link their purchase history) but you can audit vendors and mints to verify that they pay taxes. It's quite an elegant system and strikes the right balance (in my mind) between privacy and accountability for corporations. Also it piggy-backs on existing systems (operating through exchanges) and doesn't require proof-of-work. And the browser extensions are super easy to use (even easier than Flattr in some ways). > I think GNU deserves much more support then it's getting. I would recommend donating money to the FSF (if you have the means) and becoming a member. They are an incredible project doing awesome work and deserve the support. You also get free access to LibrePlanet conferences and a few other perks.
