I totally agree. You nailed it! And being a driving force for your cofounders and startup with a vision is probably more important than being a programmer. IMHO.

In my view, taking the portfolio approach is a sign of not having enough faith in any one direction.

Entrepreneurs generally have sound visions in a few specific directions unlike VCs who are generally hopeful about a wide variety of stuff but will never bet on a very select few.
