> The thing about the NoSQL trend is that it's still very valid in some areas. Even big and slow companies have some project or supplier that uses a software with a NoSQL service in it.

This is a good point and I didn't do a good job of acknowledging it in my prior comment. There are use cases for NoSQL, but to me it's a tool for a narrower set of circumstances. My default is relational, unless I have a clear idea of why that isn't the right fit.
