Have any of you fin devs out there on the interwebs had any experience with building social networks using `Stream`??

I am looking into their API for use in a golang project of mine but I am unsure about a few things...

1. Reliability
2. Scalability and the cost of it
3. General API quality, in Golang specifically but any comments are great.

It's a stretch I'm sure but if there was a place that folks would know it would be here @ devRant
