Go noob here Can actual products (Web apps in my case) be built with Go?

Yes. I am using it myself, and am about to deploy a production app. All Go.

  Out of curiosity, what are you doing for error reporting? I'm thinking something along the lines of honeybadger/hoptoad/etc -- automatic notification if the program crashes/deadlocks/what-have-you.

    Im using my own library at the moment. Might release it as open source in the near future. Just waiting on some language features to stabilize.

Sure. Go doesn't yet have any mature web frameworks like django for python but quite a bit of what is needed to build web apps is already part of Golang. (Packages net/http, html/template etc.) If I remember correctly Google switched their download service to using Go and there was a post here not long ago claiming they went from a lot of servers to merely 2 by switching to Golang. See http://golang.org/doc/articles/wiki/ http://golang.org/doc/articles/wiki/ for an example.

  Is Go really that efficient? I heard similar claims from somewhere else, and this has been a motivation for me to learn and then build something in Go. And what might be the reason for that? Speed? Parallel processing?

    While I don't have any first hand experience with Go's performance - it is not that hard to believe it will be fast enough - it is a compiled language, so no interpreter / JIT overhead like Ruby / NodeJS. Plus they try to be closer to C where it makes sense (it has pointers but no pointer math for e.g.). The synthetic language benchmarks also put it very close to gcc -O2 C performance. About the only things that need to be improved further (so I've heard) in Go are the GC, coroutine/thread scheduler and crypto performance. They are already better in 1.1 release but Crypto is still not close to OpenSSL performance.

    As someone who writes Go code professionally, I find Go code to be really easy and quick to write, with fewer bugs/LOC than any other language I've used. Both compilation and execution speed are really fast, so you have both quick edit-compile-test turnarounds similar to a scripting language while having the execution speed of native code. Not quite as fast as C and C++, but getting there. Writing concurrent code is incredibly easy with the primitives Go provides: goroutines (think of them like green threads multiplexed to 1 to very few OS threads) and channels (similar to pipes). No more faffing around with details of thread creation and teardown or an unreadable mess of callbacks (like you would have in system with event loops). So, if you've written concurrent software (like network servers) before, check it out, you will enjoy it.

  The Gorilla toolkit [http://www.gorillatoolkit.org/ http://www.gorillatoolkit.org/] adds several more useful libraries for writing web apps.

You can use Go with Google AppEngine [1], though it's experimental. AppEngine also supports Python and Java. It's a nice environment to experiment with Go, since you'll get quite a bit of free bandwidth / storage [2] to start out with: > "Not only is creating an App Engine application easy, it's free! You can create an account and publish an application that people can use right away at no charge, and with no obligation. An application on a free account can use up to 1 GB of storage and up to 5 million page views a month. When you are ready for more, you can enable billing, set a maximum daily budget, and allocate your budget for each resource according to your needs."

http://microco.sm/ http://microco.sm/ is all built in Go, as far as I know. buro9 loves it, and I bet deployment is a breeze.

We built the backend of www.healthcorpus.com in Go. It was great.
