Am I the only person here who feels like they can't relate to anyone who posts on this site?
Not relating to people on this site doesn't necessarily mean you won't be able to relate to people in your law school class. That is, I don't know that the site presents a representative sample of law students.
In my experience, many law students are surprisingly, overall, normal and unquantifiable. They don't have many commonalities other than the fact that they're in law school and, generally, do well enough academically to have gotten in and remain. Otherwise, I know people all over the map in terms of current interests, future interests, history, family life, etc.
My guess, as long as you're open to talking to people, you'll be pleasantly surprised about your classmates.
