I even posted a post to this effect where I basically summed up the most interesting part (for me) of a marketing book:
http://news.ycombinator.com/item?id=127157
In order to have a clear value proposition to get people to give you their money, you need to answer (according to the book) these questions in succession of difficulty:
Who you are / what you do / for who / because they need what thing that they can't do without you / unlike your competitors / your different in what way / which is a very important distinction (how?) and makes people care (why?).
I'd say most startups start with "who they are" and stop. Some make it to "what they do" although not expressed clearly. The part about "for who" and "why they care" never seems to be spelled out, just implied or something.
The first response is by some guy who took this as both a personal attack and an attack on the whole Y Combinator community!
Then PG comes on and says, "well such and such venture capitalist says he funds business that solve a problem the founders had."
I try to point out that that only holds true as long as that problem is one a huge market of people are also having and are willing to pay for the resolution of.
Then, in a rather futile and pointless exercise, he goes on to systematically knock about 30 points off my all-time high of 80, perhaps under the delusion that I secretly covet a high point tally so I can impress him or something.
It's like, the very mere suggestion that people need to tie their technical ability to practical solution solving for paying customers, especially in this economic climate, seems to meet with rage and fury from programmers who seem to take basic economic reality like a personal insult or something.

That would need perspective and ability to anticipate possible patterns of future development, ability to assign probabilities to multiple scenarios, etc.
All "right brain stuff". Most programmers I've come across, especially here, couldn't seem to care less as long as they post their startup and score points from peers.
