Yes. It's not just the decline of quality analysis/execution, but the actual topics are becoming dumber (and more overtly political). I wish they had a way to filter based on bylines. Generally the articles by Rohin Dhar are awesome.
If you use NewsBlur to subscribe to their feed, you can use the "intelligence trainer" feature to filter based on author, tags, or phrases in titles -- works quite well almost always. (Not sure if other feed readers have the same capability.)
The genius of the blog was taking on the surface boring topics and, through quality analysis, doing something awesome. That might be hard to identify programmatically.
