Why isn't this "authority" blog indexed?

Read this Digg item at :> http://digg.com/apple/How_Apple_may_actually_implement_Windows_support_on_in_Leopard

... which linked to a post in http://tonioloewald.blogspot.com/

For such an old blog (see the archives, which goes all the way back to 2002) with obviously good content, I'm surprised not a single page of it is indexed in Google.

Any thoughts on this?

 

Its in the index when I look.

 

Yep, it's indexed, but too bad all these posts and no PR .

Almost everything's in the Supplemental Index :> http://www.google.com/search?source...6-22,GGGL:en&q=site:tonioloewald.blogspot.com

Really weird!
