I often waste time checking to see whether any of my Amazon.com reviews have landed more helpful votes. For that reason, I hacked together a quick OSX Dashboard Widget that lets me watch obsessively without getting a browser involved. Enjoy1!
This could be a bit too rough around the edges for you; there’s no icon, it could break if Amazon updates the profile page markup, and a long name or wildly different ranking might even be enough to make it ugly. You get no warranty, but I’d also be happy to clean it up if enough others actually use it. ↩
