A little bit off topic, but this reminds me again of how much the web needs an easy payment system (as easy as in-app purchases in mobile). EFF, wikipedia, I often see notices or news of things they're doing and think to myself that I should donate. But I'm usually in the middle of something and stopping everything to take out my wallet, get the CC, fill out a form, etc. is just too disruptive. So I try to remind myself to do it later, but then forget.
