Google Reader was launched 10 years ago ago today. Though it did not live to see its 10th birthday, pieces of it still live on. Specifically FRBE (Feed Reader Backend) was Reader's backend, but over time it evolved into a reusable piece of Google infrastructure, powering the Feed API, Blogger's following feature and many other things. Thanks to an anonymous source within Google, it's possible to see that this bit of Reader is still up and serving requests.
