I've been reading Anand's articles since I was 15 years old, using his guides to put together a new rig every year. With his long history of tech publishing, Anandtech is one of the few sites on the internet I trust for unbiased reviews and news. It is sad to see him retire from writing, but I'm sure the solid team he put together will maintain the same high standards they have held for the past decade and a half.
On a personal note, I was always amazed that an Indian kid my age (32) could be incredibly versed on technology and famous to boot. I want to be like him when I grow up.
Though not mentioned in the article, he is starting a new gig at Apple.
