 * “At the time, no single team member knew Go, but within a month, everyone was
   writing in Go and we were building out the endpoints. It was the flexibility,
   how easy it was to use, and the really cool concept behind Go (how Go handles
   native concurrency, garbage collection, and of course safety+speed.) that
   helped engage us during the build. Also, who can beat that cute mascot!”
   
   — Jaime Enrique Garcia Lopez, Senior Software Development Manager at Capital
   One

 * "A small language that compiles fast makes for a happy developer. The Go
   language is small, compiles really fast, and as a result it lets your mind
   focus on the actual problem and less on the tool you are using to solve it.
   Code, test, debug cycles are so quick that you forget you are not working
   with an interpreted language. Looking at our code, you see less boilerplate
   and more business logic."
   
   — Clayton Coleman, Lead Engineer, Open Shift at RedHat

 * “Go has excellent characteristics for scalability and services written using
   it typically have very small memory footprints. Because code is compiled into
   a single static binary, services can also be containerised with ease, making
   it much simpler to build and deploy. These attributes make Go an ideal choice
   for companies building microservices, as you can easily deploy into a highly
   available and scalable environment such as Kubernetes.”
   
   — Matt Boyle, Lead Software Engineer at Curve

 * "In our tightly managed environments where we run Go code, we have seen a CPU
   reduction of approximately 10% with cleaner and maintainable code."
   
   — Bala Natarajan, Sr. Director of Engineering, Developer Experience at PayPal

 * "Tooling has always been a problem with our legacy code base... but we have
   found that Go has excellent tooling, plus built-in testing, benchmarking, and
   profiling frameworks. It is easy to write efficient and resilient
   applications. After working on Go, most of our developers don't want to go
   back to other languages."
   
   — Benjamin Cane, Vice President and Principal Engineer at American Express

 * "...when a programming language is designed for exactly the environment most
   of us use right now—scalable, cloud-based servers that are optimized for
   performance—a lot can go right."
   
   — John Biggs and Ben Popper, at Stack Overflow
