Are the days of Keyword Search numbered?

I used to sell web sites to mortgage brokers in the Pre-Google erra. At that time, being on page one was everything, and we knew how to do. One problem though, Google came along and changed the game. It's because of this experience that I've never been a proponent of SEO as the only, or even the most important way to market a blog.
