Looking at things as "business" and "technical" is part of the problem. There are "products/services" and "customers". A group of people wanting to serve a market must be able to contribute to these two things - via programming, selling, insight, connections or whatever. This is important. It doesnt matter how one does it, but contributions ought to be meaningful. These labels (business, guy or technical guy) may prevent a good open discussion and box people, sometimes too early and sometimes needlessly.
