You are welcome to your opinion, but on your suggestion I just went and looked at John Siracusa's blog and for this entire year we have: 1: a discussion about various ways you can read his Mountain Lion Review. 2: How to cook pasta. 3: summer movies. 4: summary of 2011. That's it.
He writes also on Ars. In 2012, he has posted a single article, his review of Mountain Lion.
Might I ask, and I am being completely sincere, what DO you read regularly for "perceptive analysis of apple products" that goes beyond once a year OS reviews?
