I first met Stentor Danielson when he attended worship with my former parish. He's moved away, but I still enjoy his blog, Debitage. Why? He makes me think. Just when I've gotten "too practical" for my own good, there are these philosophical -- and especially the epistomological ones -- postings that keep me from waltzing down a dead-end of thoughtlessness.
If you don't read his blog, you should.
