Brain child of one of my favorite authors, Seth Godin, is Squidoo. Read and learn.
Squidoo concept: Everyone is an expert on something.
How can Squidoo benefit you? By creating a “Lens” on a topic, perhaps what your business sells, you position yourself as an expert. And it also can improve link popularity if the lens links back to your site or blog. My suggestion is to browse around on Squidoo, create an account and claim your lens.
