Whenever looking into a life changing decision, be mindful of confirmation bias. There is a human tendency to find information that justifies what we want to believe. There is truth on the podpost. However, presenting the truth in an incomplete picture is still misinformation. I would suggest going outside podiatry if at all possible and try and talk to 2-3 gps, and their referral staff and see what they are saying about podiatry. Then try and put those pieces together with info here, the post, pm news and 2-3 shadowing docs.
Almost no pods will admit when and what they are struggling with.
Overall, I don't think there is enough secure ROI opportunities in podiatry anymore. But I am well aware that many DPM'S still love and make a great living in private practice. I used to be one. I would also not write off the angelfire podiatry posting.
I would also suggest keeping up with kevinmd, medical economics, himss, modern healthcare, and health articles from the wsj, cnn etc.
Periodically Google aca and ACO effects on doctors and private practice.
Crash a conference and sit next to a couple of conversing grey haired DPM's at lunch and casually eavesdrop. Those guys are brutally honest until they sell you their practice.
