If you enjoy the written word like I do (and hey, the spoken word while we are at it), you might enjoy these various style guides from The Times in London, The Guardian, and The Economist. This last one is also available as a book as is the New York Times' style guide.
The Economist guide just happens to be on my Amazon wishlist. A handy bit of information for you considering that my birthday is just around the corner. Hehe. If you have some time to spare, you can also do an Economist style guide quiz. You are presented with number of sentences and have to choose how the Economist would say it. What fun. I just scored 8 out of 12, which according to The Economist means that there is "Room for a fair bit of improvement." :-/ Maybe I'll move on to some other diversions.
