Hacker News Reader

Do not forget Google Commerce Search was shut down. It was a paid product, used by entreprises and pretty close to Google main focus (search) https://support.google.com/gcs/answer/163357?hl=en http://techcrunch.com/2013/02/14/google-quietly-shutters-com...

And Google Checkout (a paid product) was pulled as well. Google Wallet is a replacement in the same way that Google+ is a replacement for Reader.

I'd like to add some color to that. Google Wallet is for Digital Goods only. Checkout was for pretty much anything. (especially ecommerce)
