I use Go and love it. That's the only thing in my app achive sub ms latency. That is being sad, Go is still not as mature as other language such as Ruby, Java, Python,...etc in term of eco system around web application. Take database for example. Any web app needs to interact with MySQL, MongoDB etc. But the performance of those drivers are somehow lack behind when I compare them with other driver. MongoDB/MySQL drivers are both seems come from individual works of excellent/talented developer than official support from those database. Go shines in system/devops stuff though.
