Okay, I went ahead and did it. Over on the left, in the Currently Reading section, you'll find an Amazon link to the book that I'm currently immersed in when I'm not doing things like working or sleeping. My primary purpose was to have a semi-decent graphic of the book cover as scrounging around for pictures that fit the box was becoming a tad labor-intensive.
And yes, I do receive a small referral fee if you use the link to buy stuff. Frankly, I really don't care if you buy stuff through the link or not. I'm just too lazy to look for and edit pics.
