I think there are only a few students at my school who are even aware of this site. As most are more intent on their own studying and so on, there is usually little here to interest most of them. There are a couple of us who drop by from time to time. Otherwise a number of the posts are from former DPM students or people who may only have peripheral involvment.
It is a relatively small profession. Most would not have much interest in the SDN site, so (in my educated opinion) it is not likely to be widely known among podiatry students. Nor is it likely to offer much to those who do find it.
On the other hand it could be interesting to those who might bee interested in the DPM degree, or to other health care types who may not know anything about it. Unfortunately there are not many here who can give accurate information.
