Rest assured, it is purely a coincidence. Speaking for Zymurgy, we strive to provide the most "current" homebrewing topics in the magazine and since Cascadian Dark Ales are hot right now, it's only natural that BYO would pursue an article about them as well. As Susan mentioned in her post, if there is a particular topic you'd like to see covered in Zymurgy, please drop me a line.
Thanks for reading!
