Hated your book? How much of your life did you waste? You should get even with that author by hopping onto the latest bandwagon: Amazon's new post-it tags. Essentially, Amazon is letting registered customers put tags on product, which are essentially words that are meant to let the items sell. For example, "a great gift for your little sister". However, shoppers are rebelling adding tags such as: 'boring', 'Yawn', 'evil', and 'scumware'. What about 'Barf'. Has anyone used the word 'Barf'?
