When I first started in practice, I scorned blogs, social media (I think it was just My Space then) and any other not-in-person method of communication. I had a patient who was social media savvy, and she really helped me understand the value of being able to get important ideas out to a larger group and start a community conversation (still working on how to do that exactly).
She wrote up a nice story for Holistic Primary Care that features my journey. Check it out!
