If you want to get content as it is created and shared and in a format more flexible than an email digest, however, you’ll need RSS. For some content and perhaps for your particular reading style, email digests may be a perfect fit and they’re still in use by many web sites-if you’re interested in getting daily email updated from How-To Geek, for example, you can subscribe to the daily email here. Material from the site gets packed up in a daily, weekly, or monthly digest, and fired off via email. Historically, web sites mimicked analog mailing lists in order to deliver content. RSS is like bookmarking in that you flag the site to be used in the future, but instead of sitting statically in your bookmark folder, your RSS “bookmark” is an active entity that is constantly updating itself with new content from the saved source. Normally you bookmark a site and you have to go look in your bookmarks to click on the site to get new content. One of the easiest ways to envision RSS is that is is like a living bookmark file. You should probably handle these extra fields with care.RSS may be one of the most underutilized but incredibly useful tools around. Generally, as RSS is XML (or almost always), it's extendable, which means any publisher can extend the RSS with custom fields. Few feeds actually have this field, so I would not use it without making sure that you can't handle it missing. It should probably be used by your app if you want to extract data from the resource, without being accounted in the feedburner stats, for example. For example, Feedburner uses it to link to the original resource. The origLink element belongs to a specific namespace. This link may include tracking code or redirects that are used to count clicks and more. That's probably the element you should use if you build a reader and want to redirect the user to the site that holds the news. The element corresponds to the main link to to the resource. You should NOT expect that to be a valid link to a valid HTTP resource. There should be a strict mapping between a given entry and its guid. RSS feeds rely on simple text files, extracting important information from XML (extensible markup language).

An RSS feed is a web feed that allows applications and their users to access automatic website or content updates. The element may be a link or a URI, but it should be used to distinguish/identify unique entries. RSS stands for 'really simple syndication' or 'rich site summary,' depending on who you talk to. All of these fields have different purposes and you should use them for their purposes :)
