If you visit any of my book pages on Amazon, like Mastering Delphi 2005's page, you can now see towards the middle of the page the short version of my AmazonConnect profile, along with a couple of entries related with my Amazon blog (don't worry, my real blog will remain here!). You can also see my full profile at this link.
The technology is nothing new, but Amazon author profiles (that have to be verified by publishers) include an author biography, a blog, a calendar of events, plus lots of "buyer" information: last few titles bought on Amazon, last items in the Wish List, last visited pages on Amazon site, last books bougth from Amazon, and the like. I have two reactions.
On one side, I've disabled most of them as I see this as an invasion of my privacy. I don't buy only tech books, but also books for my kids, wife, and my own pleasure... and I really don't want people around the world to know about this. Sorry if you are curious. The same holds for my wish list or visited pages. I have left some info around in purpose, but in a very limited way (I hope).
On the other side, I'm quite impressed at how Amazon is trying to bring on board ideas from "community sites", like del.icio.us. The most obvious examples is tagging. You can now tag any book (or any other item on sale) with any tag of your choice, and you can of course browse by tag and navigate using loose associations. It is interesting to see how this turns out, and whether Amazon sales actually benefit from this.
