Before entering a medical school, I frequently used the Mayo Clinic and Cleveland Clinic websites. They are easy to navigate and evidenced based from a trusted source. When I worked as a dietitian these were the websites I directed my patients to when they had general questions. In my honest opinion, I wouldn't trust a blog or recommend one to patients. (although I'm sure your blog would be awesome!) It is so very difficult to determine people's qualifications and motivations online. Perhaps if there was some way to make sure your qualifications were verifiable? I'm also curious if this would open you up to liability. There has to be some reason most physician bloggers state "this should not be taken as medical advice, please consult your physician blah blah blah". I wish you the best of luck with this idea! It does sound interesting and useful.
I agree - "person who has their very own blog" is not a very special qualification!
I do wonder about the liability, but haven't found many answers to that. It seems people get into trouble when they dispense advice to specific patients that they are not licensed to do (a guy who was running a diabetes diet blog and taking questions, for example). I am licensed to practice medicine.
Also, I wouldn't want to write an encyclopedic blog - WebMD has done that already. More along the lines of what I posted above, also concrete advice on saving money on medication, home care for common complaints. It would be more of a preventative care blog - do these things now, so you don't end up spending money unnecessarily.
Again, thanks for the feedback.
