The nightclub analogy is appropriate. The truth is that the idea person isn't even necessary. It's easy enough for two technical co-founders to play that role, the rare exception being an idea person with unique experience in a niche industry.

The idea person who invests a few months in learning a language is infinitely more attractive to a technical type. Nobody wants to be in a partnership, knowing that someone is depending on them 100% to accomplish the overwhelming majority of the work involved.
