"Overall, the experience was positive and I would seriously consider using Go for writing server side of web applications as it provides a right balance between speed and memory efficiency of the running code (much closer to C than to e.g. Python) and speed of development (much closer to Python than to C)."

It seems these days that there is a confusion between the web server (often a reverse-proxy), the web application and the thing in the middle (gateway/pipe/container/app server). While I would certainly consider Go for the implementation of a reverse-proxy or an app server, it isn't clear that Go is a good choice for the web application itself, especially when you consider that most of the time is spent in the DB and in the cache...

Anway, the article mostly talked about Go and not about Python...
