I HATE what modern technology has done to magazines. I don't like all of this distracting interactivity. I'm not reading a text book. I want the article and some pictures. Men's Health is a prime example of screwing up a great magazine.
What I've learn in my experience in graphic design, marketing and logo design, never use a letter to help brand your product. When you let people guess what the letter means, they will usually think the worst. "Cheap".
