I'm a huge fan of the work of William Z. Shetter, a retired professor of Germanic studies at Indiana University, and author of a number of books on the Dutch language.
He writes some of the most literate, informative and delightful essays about language I've run across.
If you enjoy reading about the structure of English, how it developed, the similarities, and dissimilarities, with other languages, flavored with a wonderful bit of cultural insight, check out the 165 essays at his web site.
Copy editors should make note of essay 19:
British Left Waffles on Falklands
Why do some headlines sound so funny? but they are all worth your time.
Professor Shetter's low-key site has several fans around the Internet, including Oddity59 in New Zealand, linguistics blogger Neal Whitman and Languagehat.
