The yin and yang becomes more amusing when you think that the site's title suggests an appeal to the first group: the techies for whom this is a passion.

Yet it would not exist without the second group because it was started by an investment fund/startup incubator.

I agree with you, I love both perspectives and the passions they ignite. I am squarely in the first group, and I love reading about the real life realities of product design/management, pitching, etc.
