From the job ad:

The Wall Street Journal is looking for an experienced, confident journalist to helm a new online project that will reshape how the Journal covers business news.

This person will be responsible for a real-time news effort that will “blog the business day,” with an emphasis on the biggest stories of the moment. Each day will be different, meaning this real-time columnist should have a broad range of interests be it technology, consumer brands, air travel, natural resources, health care or the completely serendipitous.
