It's funny that they argue that they dumped the JVM derivatives like Scala, but wouldn't exactly tell why, nor support their argument with any sort of data/logs.
I am genuinely curious to know why they chose Go over Scala. If it was the syntax, etc. I can partially agree because it's one of scala's weak points, but then they pitch the main reason citing performance, so I'm genuinely curious to know.
Exactly, you know, my advice would be to take these blog posts with a pinch of salt. There is something called as the 'mob' mindset. The mob in general can be easily manipulated to believe in something that is not true. (Remember Julius Caesar?). For example, a year or two ago we saw the whole world of start-ups adopt MongoDB with so much vigor and almost everyone started writing "Why we moved away from MySQL to MongoDB". And two years later, we have now a bunch of posts saying the opposite - "Why we moved away from MongoDB..", etc. The same thing applies to Node.JS and Go too. They are still new technologies, so I think they deserve some time to be tried and battle-tested, instead of writing zero-data driven blogposts like these at an earlier stage. I would have been much happier to have read something like "After x years of using Go, Erlang and Scala, here is our comparison on what works well and what doesn't and how each one of them perform under different conditions" instead of "Hey we just reduced our server count to 2 using Go, hence it's better than everything out there.."
Personally, just like you, I think these guys could have achieved more with Erlang or Scala, but given the fact that they chose Go because it works well for their architecture, I am not complaining.
