I suspect you will find that if you are not capable of making this a PR issue for Google they have absolutely no desire to talk business with you, because you have nothing to offer them. (An example of someone who could make it a PR issue: 37Signals, when Google duplicated the core functionality of one of their products as a tech demo.)

Google is not a kind or gentle corporation. They're a huge multinational whose business is built on a combination of pixie dust and the ground-up bones of folks whose business models came into contact with Google products.

That said, if you're serious about contacting someone, find someone inside the Googleplex (cough if only their were a site where you could get LinkedIn in with professional peers cough) and get them to make an introduction to the Product Manager for Reader. This is essentially the way you do inbound contacts targeting any large corporation.

Again, just telling it to you straight: it is vanishingly unlikely that you're going to succeed in this.
