WayPath has released the Beta version of their Waypath Related Stuff This is a very interesting extension of the Waypath algorithm. Waypath lets you search for related information from their collection of RSS feeds through either their web interface or the use of Plug-Ins for various weblog applications. This extension allows the search of related books from Amazon.com. Even though this might not be very useful for every blog item, somewhat static informational posts can definitely benefit from this addition. I am about to use it to put some books up for my Regular Expressions Tutorial. If and when they release the XML-RPC/REST-XML methods for their new search, I will try to write another plug-in for WordPress and php based blogs. (my previous Waypath plug-in was a relative success) Worthy of mention is that if you have an Amazon affiliate ID, you can include that in your list of books and make money off the click-buys!
