Exporters include insufficient examples

[DazWilkin]

The documentation suggests that, running these examples, will result in metrics to observe.

This isn't so.

https://opencensus.io/exporters/supported-exporters/go/stackdriver/
https://opencensus.io/exporters/supported-exporters/go/prometheus/

I cite the two services with which I'm most familiar but assume it's true of all of them.

The exporters are created correctly by the code and view.Registered but that's all :-(

Some form of view.Register and stats.Record needs to occur for these to emit anything useful.

Recommend adding a little more code.
Perhaps simply reusing the existing example:
