Jeff Atwood, the author of the aforementioned blog is awesome. He's as good as Joel On Software (todo: link to the review page here). I found him quite late - I follow Joel for so many years now. Jeff is a must for everyone who calls himself developer. He's smart, he writes very well, he's practical. The last thing I read was a piece about keyboards. And he references old articles about keyboards - he's written on the subject like 5 times. Wow, that's kind of refreshing.
A must: Coding Horror.
