Those are awesome ideas! We had never thought of loading up on Watsi Credit (with a large, one-time donation) and I think that's a super cool option to offer donors. No doubt we are going to see a major decrease in traffic after this HN post, and working on ways to retain donors is going to be our next big challenge. Thanks again for the feedback and support, we all really appreciate it! (And if you do come to SF, the beer offer still stands :)
