I echo the previous sentiments. I learned as much from these forums as I did from almost any other source, especially during the early part of the residency/interview learning curve. Guys like Dave Russo, Ligament, Stinky, and others have been invaluable sources of information, taking time out of busy schedules to answer the million and one questions we all have. More importantly to me, I've developed friendships from these interactions, and in my opinion that's the great part. I think one of the reasons PM&R as it currently exists is such a great field is that it is just full of nice, caring people...
