The only substitute for traction is past traction (on previous startups) or a very big credential (as being on YC or being early employee on a big hit - Facebook, Google, etc). And this narrows the audience to only a few individuals for whom these tactics might apply.
Not by chance Paul Graham recent essays are aimed at this YC batch aproaching Demo Day. And, as interesting as is to us, regular folks, reading this; it sounds like reading advices from a pro driver on how to drive a Ferrari. They may be somehow useful, specific tips that you must know if you want to drive a Ferrari. But you first must own a Ferrari. Before you do it, they are just fiction.
And if you do have traction, I guess all these tips will have just a marginal influence on the outcome. Posts from VCs and succesfull fundraisers always seems like hindsight rationalization about why it worked. Forgetting that traction was the single most important reason by far.
I mean, traction is 99,9% if you are a regular founder, not a star. So wondering about the 0,1% is more of a Maseratti problem.
