Adrian I agree about Wikipedia, I finally contributed to them because of the amount of benefit I have derived from their existence.
I have looked into the Electronic Frontier Foundation, the one thing that has held me back is that they spend a bit more on administrative costs than most foundations I normally contribute to (I like as much of my money going to the cause as possible). This segues to my plug for Charity Navigator, which I always try to use when evaluating a charity.
