Ben LaMothe argues that journalism students should take liveblogging 101: 

Saying that you’re going to live blog an event, and actually live blogging an event are two different things.

Reporting on an event for a story is not the same thing as reporting on an event as it is happening, sending out bursts of information every couple of minutes.

It’s not the same skill set, but it’s something that reporters are increasingly likely to have to do at some point in their careers.

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.
