I liked So Long, and Thanks by Oliva Judson who, until the end of June, wrote about "the influence of science and biology on modern life" for The New York Times website. In a farewell post prior to taking a year's sabbatical, she wrote about her writing process. Though, really, it seemed more to be her pre-writing process. As with all writers, the actual slogging through the writing remains a mystery.
Her post made me wish there was a database for fiction writers where we could go read material related to our ideas.
I found So Long, and Thanks by way of Practicing Writing.
