Just when you think you know what a blog is, amazon.com comes out with plogs. What's a "plog?" The amazon folks are kind enough to tell you that it's a personal blog designed to "enhance your shopping experience." And, you know what, it does!
When I go to amazon.com, a page comes up called "Joyce's Plog" and tells me about a couple of new books that have been recently released. I'm a fan of the DaVinci Code and amazon told me that one of the books was similar so I checked it out. Here's the good news and bad news for amazon -- Good: they told me about a book that I thought I'd like to buy. Bad: there were enough marginal reviews also on amazon that I decided not to. Net sales for amazon: 0. Net result for me: increased appreciation of amazon. Overall, amazon's plogs look like a plus.
