As I said earlier some of us have already been doing this. For me mainly commenting at length on blogs from time to time, and on the reddit, as well as here and on Twitter. Come to think about it, I’m quite a PR engine and have also approached quite a number of people online and introduced them to the project.
For your article you might want to take a look at this from Ephi (see below). There are other decent posts around (this thread probably links to some good prose). I think this is worth doing, but the real impact of such things won’t be seen until there’s a product.
