LATE TO THE PARTY
Well, it looks like I'm not the first Mormon lawyer (or, more specifically, "Mormon soon-to-be lawyer") to get a blog (no surprise there, I guess). Nate Oman, who is a graduate of Brigham Young University and the Harvard Law School, has started Tutissma Cassis. His previous blog A Good Oman is still available.
Nate also has The Kolob Network, a website intended as "a place where scholars and students of Mormon studies can exchange current research." Both sites sound interesting.
