I left a note that he (like the EFF and the ACLU) should have a recurring donation option, or at least an option to receive a once yearly email asking for a donation. There are many people that would happily go with a recurring donation if that option were available.
I just chipped in $25.
Edit: Over €10k more in the hour since this comment. It's now 2/3 of the way to the funding target.
It's just that it takes a lot of media attention to get you to your goal plus a lot of the donations a coming from regular developer who understand the importance of this instead of the big companies profiting from this software.
Imagine all the workflows that depend on verified encryption signatures like Debian, Ubuntu, etc and that's just software distribution, not counting privacy issues like journalists, political dissidents, whistle blowers, etc using it for secure communications.
It was pretty easy to donate, took me less than 2 minutes. I encourage everybody that is able to make a donation, however small, every euro counts.
And, as others have pointed out it is easy and you can choose between cc and PayPal.
Really happy to see that this post on HN has traction, and delighted to watch the counter go up. GPG and other security projects need a way better tech PR push.
Interesting to see more people have donated so far in 2015 than the whole of 2014.
