Academia in mathematics is not always different from academia in medicine. There are plenty of aspects (publications, career, PhD supervision, etc) that are shared across disciplines. That's the whole point of this site. And this is very real.
EDIT: For instance, consider your question Are there Conference Proceedings that have impact factor?. You just tagged it with "medicine", although the notion of Impact Factor is common to every publication-based field. walkmanyi's answer (that you accepted) is not specific at all to medicine. My answer is actually only for computer science.
In other words, your question is very generic, and could interest any one who cares about publishing into a conference. However, now, it has the tag "medicine", which might make some people think that it's a medicine-specific question, and ignore it. I can't see anything gained by adding this tag, but I can clearly see what you've lost.
In the end, it's your question, so you can do pretty much what you want with it, but please be aware that tags that are considered as unnecessary might be removed.
