Me, I’m a law student, studying law.
I came here to learn general philosophical principles, because law touches very generally on the realm of philosophy ALOT. By seeing the major dissent points in philosophical debates, I get a quick overview of what a topic is, what it’s differences and samenesses are, as well as a general feel as to the opinion on a particular topic, PLUS some of you post up-to-date information on certain subject matter, which can serve very usefully in legal discussions at law school… 
So, what do you do?
