Awesome speaker. Love the style / speed / approach. I haven't played with go-kit yet enough. I've toyed around with Kong (api middleware with similar hooks but it's Lua+other stuff), Istio (service glue, very new), Buffalo (different approach to Go services than go-kit) and other tools around this space but I suppose completely unrelated. Not trying to do a review, just wanted to say something other than "go-kit seems neat".
