Which blogs about WordPress are worthy of man’s attention?

I'm afraid this topic won't answer the question from the title. Rather than that, I hope some good tips will be shared in comments. What do you read (with pleasure)?

Because I really don't know. Almost 10 of 10 sources are… worthless. Currently, I'm subscribed to these:

• Mark on WordPress – Publishes not often, but holds a certain level of quality…
• Pressed Words – Kind of interesting stuff aggregator. Some of tips are worthwile.
• WordPress Development Blog – Just to know what's new.
• Planet WordPress – Again, aggregates several sources. Mostly uninteresting but sometimes hits.
• WordPress Garage – I'm not really sure but I think I saw there some useful information.
• _ck_ says – Although it's not always on topic, I like this source.
• PlanetOzh – Good proportion of worthy articles.
• Nerdaphernalia – One of the best sources of this time. Stephen writes quite often, holds some level of quality. I wish more blogs like this.

(I'd like to keep this list up-to-date.)

And now: please, tell me what's worthy of man's attention.
