Now... I actually agree that we can do more to help with questions that are less black and white. It's harder than it sounds - being a little rigid, and downright intolerant of questions that descend into religious debate "which language is better overall?" is a key part of what makes SO and our other sites work. But, I completely agree that we could probably do more to help more with a lot of more subjective or nuanced questions, and we're devoting a lot of energy to figuring out how to do so without undermining what's working well today. In summary, I agree with your point. :)
As to Startups, the main issue wasn't just questions per day. We have a lot of sites with less activity that we think are doing really well for their communities.
