在门户网站大行其道,人们已经习惯通过搜索引擎来获取新闻资讯的今天,一种全新的资讯传播方式已经悄悄地来到我们身边,仔细观察一些网站,你可能注意到一些被标记为"XML"或"com" target=_blank title="http">http://www.66of.com" target=_blank title="com" target=_blank title="http">http://www.66of.com" target=_blank title="rss">rss">com" target=_blank title="http">http://www.66of.com" target=_blank title="rss">rss"的橙色图标。

首先您一般需要下载和安装一个com" target=_blank title="http">http://www.66of.com" target=_blank title="com" target=_blank title="http">http://www.66of.com" target=_blank title="rss">rss">com" target=_blank title="http">http://www.66of.com" target=_blank title="rss">rss阅读器,然后从网站提供的聚合新闻目录列表中订阅您感兴趣的新闻栏目的内容。订阅后,您将会及时获得所订阅新闻频道的最新内容。 对于一般用户来说,用com" target=_blank title="http">http://www.66of.com" target=_blank title="com" target=_blank title="http">http://www.66of.com" target=_blank title="rss">rss">com" target=_blank title="http">http://www.66of.com" target=_blank title="rss">rss订阅新闻可以像使用Outlook Express收取订阅的邮件一样简单;而对于Web应用程序的开发者而言,com" target=_blank title="http">http://www.66of.com" target=_blank title="com" target=_blank title="http">http://www.66of.com" target=_blank title="rss">rss">com" target=_blank title="http">http://www.66of.com" target=_blank title="rss">rss的工作过程也不是那么复杂,至少比大多数其他常见的Web技术都更容易被理解和被实现。 有人认为,com" target=_blank title="http">http://www.66of.com" target=_blank title="com" target=_blank title="http">http://www.66of.com" target=_blank title="rss">rss">com" target=_blank title="http">http://www.66of.com" target=_blank title="rss">rss的初衷似乎是为了给邮件列表订阅服务以致命的打击,若从com" target=_blank title="http">http://www.66of.com" target=_blank title="com" target=_blank title="http">http://www.66of.com" target=_blank title="rss">rss">com" target=_blank title="http">http://www.66of.com" target=_blank title="rss">rss的应用方式来看,这几乎是不可避免的。但从实际效果来看,com" target=_blank title="http">http://www.66of.com" target=_blank title="com" target=_blank title="http">http://www.66of.com" target=_blank title="rss">rss">com" target=_blank title="http">http://www.66of.com" target=_blank title="rss">rss最火爆的应用并非是商业信息的集中订阅,而是个人通过Web实现的信息聚合,一个典型的例子就是各国的网志作者(Blogger)首先成为最普遍的com" target=_blank title="http">http://www.66of.com" target=_blank title="com" target=_blank title="http">http://www.66of.com" target=_blank title="rss">rss">com" target=_blank title="http">http://www.66of.com" target=_blank title="rss">rss应用人群。
