Finney has links set up on her blog to Amazon to purchase her book, which hit the shelves in May of this year. Next to information on Finney is a "plog" button. A what? Here's how Amazon describes it:

Your Amazon.com Plog is a personalized web log that appears on your customer home page. Every person's Plog is different (hence the name) and just like a blog, your Plog is sorted in reverse chronological order. Each post also gives you the opportunity to provide feedback to the sender as to whether you liked the post or not. This feedback loop means your Plog becomes even more relevant and interesting over time. Your Plog will appear if you are logged into our web site and is visible only to you.

Finney's information includes posts, upcoming book tours, reviews and even alerts when she's added more photos to her Flickr account.

I like the idea of plogs because it helps connect customers to one another and make something as huge as Amazon seem slightly smaller and more sociable, and it's a great way to keep updated on favorite authors and products.
