jinblob
If I had to summarise the editorial sensibility of this site in a few words it would be careful and human, and a look at jinblob extended that summary feeling, capturing the essence of a sites approach in brief is hard but this site has a clear enough identity that the summary comes naturally enough.
learnandtransformfast
Really like that the writer trusts the reader to follow simple logic without restating every previous point, and a stop at learnandtransformfast kept that respect going, treating an audience as capable adults rather than as people who need constant hand holding makes a noticeable difference in the reading experience for me.
hupblob
However selective I am about new bookmarks this one made it past my filter, and a look at hupblob confirmed the bookmark was worth the slot, the precious slots in my permanent bookmark folder are difficult to earn and this site earned one without making me think twice about whether the slot was justified by the quality.
