The main problem with technology coverage is you have one of 3 types of writers in the space:
1. Prosumer/enthusiasts who are somewhat technical, but mostly excitement
2. People who have professional level skills and also enjoy writing about it
3. Companies who write things because they sell things
A lot of sites are in category 1 - mostly excitement/enthusiasm, and feels.
Anandtech, TechReport, and to some extent Arstechnica (specially John Siracusa's OS X reviews) are the rare category 2.
Category 3 are things like the Puget Systems blog where they benchmark hardware, but also sell it, and it functions more as a buyer information.
The problem is that category 2 is that they can fairly easily get jobs in industry that pay way more than writing for a website. I'd imagine that when Anand joined Apple, this was likely the case, and if so that makes total sense.
When Andrei Frumusanu left Anandtech for Qualcomm, I'm sure he was paid much more for engineering chips than he was for writing about them, but his insight into the various core designs released for desktops and mobile was head and shoulders above anything I've seen since.
It's a shame that I can't even find a publication that runs and publishes the SPEC benchmarks on new core designs now that he is gone, despite SPEC having been the gold standard of performance comparison between dissimilar cores for decades.
