Qualities of a good cofounder

I think this is very wise and bears repeating:

"Complementary. If you have an idea they expand on that idea. If you’re a bit too liberal they’re a bit too conservative. Complementary should not be confused with diametrically opposed. There is such a thing as too different to get a long. A good example of a complimentary founding team would be the two Steves of Apple fame."
