I think different personalities tend to be drawn to different specialties. The EM forum is always pretty damn active too. It's hard to say or pin down. I do think my IM colleagues as a group tend to be more lame - not only on the interwubz, but also in real life. The gas guys seem to appreciate the profession more as a job, not one that they take lightly or anything, but just something they do so they can make some money and do other things that they really want to do. And it's a way to not be a real doctor - and before I get a bunch of flamey responses from some gas peeps - what they do requires a doctor level education and training, it's not time to be ****ing around with patients given their job description, but if you're not spending your time diagnosing, treating, and following disease, I have a hard time seeing anyone as a "real" doctor who doesn't do that. And so you have the personality that is drawn to that kind of thing versus the type that is drawn to IM. And there is something about that personality that makes them more chatty on internet web forums. It seems to me most IM people are kind of lame and see this place as a means to an end - get info - and have no real desire to give anything back to anyone else, not really. It's kind of a d-bag thing about IM, no real sense of community, and you'll see this in the hospital. One medicine guy will not generally hesitate to throw another medicine under the bus if he thinks it's necessary. We don't stand together. Interestingly enough, you generally will see the gas folks at any institution in a united front no matter what.
So what gives?? I don't know. I think I made things more muddy than clear.
