You are totally right, most of the stuff that really hurt us was Rails middleware magic, not Ruby itself. I should have been more precise -- grumpy rails bashing, not grumpy ruby bashing! FWIW we still use Ruby on Rails for our website and it's great for that.

I'm hoping to get some followup posts from the backend eng team on specific interesting problems we ran into during the rewrite.

& yes deploys with go are the freaking bomb :)
