> Apart from Google (who uses it for Youtube), Go hasn't really been used in large projects.

I don't know how large each of these projects is, but a growing number of companies are using it for serious projects:

Why I went from Python to Go (and not node.js)

I've implemented something similar in the same manner (over-riding `new`). The original idea came from here: http://backstage.soundcloud.com/2012/06/building-the-next-soundcloud/

One implementation detail I ran into is how to detect dupes. When you have Backbone Models, this is easy: every model has an `id`. But say you want to apply this same singleton behavior to a Backbone Collection, which don't have natively have `id`s. I saw two options:

1. Assign an `id` to the collection when instantiated (could just be a string, so that you can force a singleton only when you desire it).

2. De-dupe based on `instanceof` checks. The downside here is you always get a singleton even if you might want a one-off instance of a collection.

Are there any other options? Can your Identiy Map handle collections?

Soundcloud wrote a blog post http://backstage.soundcloud.com/2011/04/failing-with-mongodb/ about the specifics of how they failed in implementing an analytics platform in MongoDB, then went with Cassandra (and why). I have been at a company where it was on developers to deploy mongo clusters, setting up logging can suck, but still there are no numbers or even application integration specifics here. As someone pointed out - manual denormilization can suck. There are options like MongoHQ and Heroku though so this shouldn't resolve to "don't try a new data store its hard and possibly buggy".
