I posted a couple of days ago about Amazon's new feature where they allow users to sign up for email notifications when an author puts out a new book. Apparently they're doing a staggered feature release (thanks Amanda Brice and Daniel Arenson for pointing that out). In plain language, that means some people are seeing it, some aren't, and some see it in one browser or one device but not others.
This is something I sent them a suggestion for about two years (or more) ago, so I'm hoping it leads to more sales and helps build reader loyalty. Most people will follow (and buy) an author they like if it's made easy for them. Hopefully this'll do it!
