The first day of the 30 Day guide is a short article from Harvard Business Review on the real job of data scientists.
It's a solid article, covering the idea that the point of data collection is not just to throw out a whole lot of data, but to use it to tell a story. This is done primarily through making sure your presentation is visual and accessible...both sold ideas.
This is certainly good advice, especially if the data you're pulling is data related to a problem with no solution or getting information no one knows. When data is being pulled to support a particular agenda, the "data scientist as storyteller" idea could get dangerous, but I'm not sure most big data is being used that way at the moment (though obviously instances of this will be more high profile).
Overall impression: good for a read if you're interested in data science, short piece, easy reading
