So you know how if you want to look up when a book's coming out on Amazon, several of those pages are now accompanied by the authors providing their own personal blog entries (which are often copied from their own sites or Myspace pages)? Well, as of this week, that feature - known by the even more awkward name of "plog" - is no more. Instead, as Amazon's editors write, the feature has been replaced by Amazon Daily, which unlike the Plog, is available to all Amazon visitors, whether you're signed in as a recognized customer or not. And instead of Amazon doing the personalizing, now it's up to the user to decide. On the surface, it seems a good move that might get Amazon's users to interact with the site even more, but it's very much a work-in-progress - just what the company's parroting at the moment...
