Google AJAX Feed API

Google announces the Google AJAX Feed API in the morning of Monday, April 16, 2007. It is an API that takes the pain out of developing mashups in JavaScript. Now you can mash up feeds using only a few lines of JavaScript rather than dealing with complex server-side proxies. Check this out http://code.google.com/apis/ajaxfeeds/ and http://googleajaxsearchapi.blogspot.com/. For PHP, there is a library called Magpie RSS. For Ruby, there is a built-in standard library and FeedTools.
