Bit of a monster reply! Have you thought about turning it into a post so you can make some steem?

On the first point - tech v. biz - we may be looking at opposite ends of the telescope - I'm wondering whether it can be separated entirely - from 90% -> 100%. you might be thinking more of 0% -> 50%. And once we get beyond one person, we've possibly formalised a relationship between a business person and a tech person. That is, more people doesn't make it disconnected, it just means that the techie thinks more about tech. We hope.
