oh that's actually really good to hear - my team has a lot of backend services in Perl (yeah..) that we're moving to Go :)
It's like being in the late 90s and replacing your existing infrastructure with Java hype, except with a language somehow worse but justified with Rob Pike's pseudointellectual bullshit.
Available since Fortran and not a Go only feature.
(I'm sure you're aware of this, I just didn't want to leave the impression there's _no_ community.)
I do think Go has a decent niche for backend services similar to Erlang but with a much easier learning curve (and more available talent). Sounds like you're actually using the right tool for the right job.
