I've learned that Elif Batuman is a woman. I had assumed, as the post below makes clear, that she was male.
This is not the first time I've done this. A few years ago, I spent a lot of time on the craigslist writers forum and found out that one of the people there I had assumed was male was actually female.
What do the two share? Obviously formidable intelligence. And a certain forcefulness of style.
