This is a good blog. It's about productivity. It's written by Matt Perman who works for Desiring God. It's called What's Best Next. What's it about? In his own words:

"This blog is about two things: (1) how to best manage our lives and work, and (2) how to best think about the way that the businesses and non-profits that we work for — and communities that we live in — should be led."
