Gary has a lot of really great content, especially on American Airlines, which is why I follow his blog.
The proofreading and grammar, on the other hand, are often so bad -- by far the worst among the blogs I actually follow -- that I sometimes have to reread a passage several times to understand the point that's being made.
I don't understand the point of those "news aggregation" posts either, but I guess that's an entirely separate topic.
