Which Type Of Programmer Makes The Best Co-founder?

I think the answer to the question is "the right one." Arbitrary classifications of sophisticated skillsets attempt to reduce the decision to a rule of thumb. That's just not really possible.

Beyond that, I think the classifications are pretty off base. The idea that hackers build open source yet are rarely trained computer scientists is pretty far from reality, for one thing.

I think personality fit and work ethic are more important distinctions than academic pedigree or past work experience.
