@Hiten, do you really look to your investors for guidance on design and marketing? Those seem to me to be your personal strengths.
All this to nitpick on one small point in the original post. Dave naturally writes for the funding audience so that is his target of the rant. His general point I agree with.
Also, while I might take money from an investor who doesn't have experience in these things, I wouldn't take money from one who doesn't have experience, yet insists on being involved in design and marketing decisions. It's amazing how many people feel the need to put their design/marketing stamp on a project, despite their complete ineptitude in those areas. I've seen it kill more than a few good ideas.
