This week's social-media PR disaster comes courtesy of BrandLink Communications, where a vice president referred to a high-profile blogger as a "fucking bitch" in an email that was accidentally sent to the blogger. The blogger in question is Jenny Lawson, best known as "The Bloggess" and named by Nielsen as one of "Top 50 Most Powerful Mom Bloggers." She recently received a poorly worded pitch from the agency about the Kardashians, and she sent back her usual reply—a picture of Internet man-meme Wil Wheaton collating paper. The BrandLink PR rep, "Erica," responded a bit defensively. But it was the vp, "Jose," who stepped well over the line with a reply-all calling Lawson a bitch. She wrote back, prompting Jose to dig himself a deeper hole by replying that she "should be flattered that you are even viewed relevant enough to be pitched at all." Lawson has more than 168,000 Twitter followers, and her blog is read by hundreds of thousands. Her relevancy isn't exactly in short supply. But Jose's might be. Lawson updated her post about the kerfuffle to note that top-level executives at the agency "are aware and are handling it the best way they know how."
