Have you ever thought about creating an e-book or guest authoring on other blogs? I have a blog based on the same ideas you discuss and would really like to have you share some stories/information. I know my visitors would enjoy your work. If you're even remotely interested, feel free to shoot me an email.
You can definitely see your expertise in the work you write. The arena hopes for even more passionate writers such as you who aren't afraid to say how they believe. Always follow your heart.
