Ask HN: Best data analysis blogs?

I'm interested in data analysis and I'd love to learn more about it. What are some good blogs to pop into my RSS reader? I only have Paul Butler, the facebook intern who mapped peoples friendships onto a glove, so far. My goal here is to get inspired to do data analysis while also learning about it. Thanks in advance!

The OKTrends blog has some pretty great articles regarding trends taken from OK Cupid's dataset: http://blog.okcupid.com/
