The amount of bitcoin fans who are pestering Amazon is a drop in the bucket compared to the amount of people who either a) aren't even aware of bitcoin yet ...
Then wouldn't Amazon having a Bitcoin icon on their payment options list inform more people that there was this thing called Bitcoin?
This is
partly what we need, right? We need more people to at least be aware of Bitcoin. Even if 95% of people see the logo and shrug it off, the other 5% that show interest (possibly young, tech fashion conscious people) could amount to a
lot of new Bitcoiners.
