I also tried posting on the article with no success.
I make a distinction between an English blend and one with Latakia. I wouldn't class Mac Baren's Latakia Blend or McClelland's Samovar as English, for instance. There's a difference.
However, I tend to think of an English blend as a loose recipe consisting of a Virginia base and a noticeable amount of latakia. I understand this was born out of antiquated British law, but that's etymology for you.
I feel that it's unnecessarily confusing to throw out this definition in place of one that classes solely according to national geography. By this reasoning a 20 year old tin of Nightcap would be considered an English blend whereas something current would not. Any old tin of Peterson would be English and any current tin would not.
To me, an English blend is simply a style with a fairly reliable definition.
