What are some less known blogs I can add to my feed?

Hello. Happy friday! Setting up my feed reader again. The popular blogs are popular, so I've added as many of them as I knew. I want to know about some less popular blogs too with good content. Got any suggestions? Thanks!

What sort of blogs I am after? To quote HN, "anything that gratifies one's intellectual curiosity." If it's good for HN, it's good for me.
