Blag Hag Jen McCreight points out that Google is now tagging pages by reading comprehension level. And you can get a nifty little breakdown of pages by comprehension level for individual sites, using Advanced Search.

Denim and Tweed pages, sorted by reading comprehension level.

Standards for comparison are in Jen’s post. Nature.com gets 3%-22%-73%; Blag Hag 90%-9%-0%. I would gloat about D&T’s relative similarity to Nature, but I’m not sure this is the sort of thing about which one gloats.
