Looks like Amazon has been upgrading their author community capabilities, now officially called “Amazon Daily”, and registered site visitors can customize their Amazon Daily home page to include information about favorite authors and topics:
Amazon Daily home page:
http://www.amazon.com/gp/daily/
Manage favorite topics:
http://www.amazon.com/gp/daily/subscriptions/?view=tagBlogs
Manage favorite authors:
http://www.amazon.com/gp/daily/subscriptions/?view=artistBlogs
Even has an RSS feed, reads like a blog compilation, really cool.
