If you subscribe to Freakonomics, you probably already know that it's moved to the NYTimes domain. Stephen J. Dubner and Steven D. Levitt are the blog authors, who co-wrote the book that goes along with the blog. I read the book, which dug into data and revealed a lot of interesting things like sumo wrestlers cheating and race/career correlations. Admittedly though, I totally forgot that there was a blog until I saw the ad on the NYTimes site.
I think this'll be great to promote data awareness just as the book has. Of course, now on NYTimes, a lot more people are going to be reading the blog.
One downside though, being on the NYTimes site, it's a limited feed, and that's just kind of annoying. Wah, wah, wah. Yes, I like to complain sometimes.
