I'm surprised this is at the top of hacker news... Is there any innovation here? Seems like a "me too" product, or am I missing something?
Conversion is everything for online merchants. Identifying customers early in the shopping experience allows better marketing, better engagement, and higher conversion. Plus, to be able to pay again in 1-click is huge (no additional login, no entering credit cards). So ultimately it means more $$ for merchants.
Yea. It's Amazon. They're kind of a big deal.
