最近了解到了Google推出了一系列跨站api比如google maps，google rss reader，注册了个Google rss api,弄了个例子
<script type="text/javascript" src="http://www.google.com/jsapi?key=ABQIAAAAEAHtmRfduFSECEeOfVUl2xSl8kdlZdkwMPlCmkDZ0isPAf6vxRQFenoaNqpmcEx7hbQeH8xumONyNA"></script>
    
<script>
google.load("feeds", "1");
function initialize() {
var feed = new google.feeds.FeedControl();//创造feedcontrol对象
feed.addFeed("http://hi.baidu.com/afcn007/rss", "My Blog");//第二参数，标题名
feed.setNumEntries(5);//文章数目
feed.draw(document.getElementById("feedControl"));//文本输出对象
}
google.setOnLoadCallback(initialize);
</script>

<div id="feedControl">Loading</div>

baidu就是不搞类似api,也许还是不重视web吧
