I switched from ruby to clojure because jvm is awesome
and it's a lisp and I also use coffescript, backbone,
requirejs and raphael. I've been using this stack for
about a month and a half, it's awesome.
Does this help? How does this help you solve your problem? I'm going to go with "It doesn't". All of these posts boil down to that form.
The good ones start with: "Over the last year we deployed [insert stack] into production..". And then tell me what sucked because not everything is awesome.
This is very cyclical. We're in the honeymoon period with some of these technologies. Two years ago you saw a lot of posts proclaiming that NodeJS and MongoDB were fantastic, world changing technologies.
Now you see a lot of posts saying "We're switching from MongoDB to Postgres/Riak because of X, Y, and Z". I suspect we'll start seeing similar posts about Node.js very soon.
No telling what will happen with Go, but just enjoy the honeymoon period for what it is and stay tuned to find out what happens later.
