What is RSS, and What is a Feed?

RSS stands for Real Simple Syndication and is one of the most common ways internet publishers push out new online content. While it is easy enough to simply visit the sites, blogs, and online magazines that publish content you like, it is easier than you might think to put your computer to work fetching content for you. Many websites provide at least one of the most common Syndication feed types; in fact free tools like Blogger or WordPress can create websites that can allow nearly any user to syndicate content with ease.

RSS files are not particularly complicated… in fact they are easy to code and update by hand, even though they are usually automatically updated by publishing software. Illustrated above is a simple RSS .xml file from Wikipedia. Websites can have multiple RSS feeds, allowing readers to subscribe to various sub categories of content from sites, for instance: subscription by author, tag, category, or in some cases, a simplified “lead story” only subscription hitting only the highlighted stories of the day. In every situation, the feed is essentially a list that will tell a program where to find the content you want. Subscribing is as simple as finding the subscribe button, clicking the RSS icon, or typing a URL. Read on!

Subscribe, and Let Content Come to You

So how do you subscribe to websites? You’ll need some form of application, either on the web, in a stand-alone application, or an app on your mobile device. Many websites like How-To Geek have an obvious “subscribe” button. But applications also allow for manual entry of RSS feed website addresses.

If you can’t find a “subscribe” button, you can go to your Feed Reader and simply “Add a Subscription.” Here’s how it looks in Google Reader.

You can copy and paste a website into the tool, or type the website you’re hoping to subscribe to.

Incredibly enough, it is no more difficult than that. However, before you can subscribe, you’ll need a program or service to read your subscriptions. How-To Geek has helpfully compiled a list of 45 Services, Sites, and Apps that can help you find, subscribe, control, sort, and read your favorite sites on a daily basis and stay up to date like a true geek.

Web-Based Feed Readers

Some of the best readers are entirely web-based and are tied to accounts with various websites, and not to applications on any one computer. The benefit of this is that you can subscribe on one computer and read your subscriptions on another. If you like to read your favorite webcomics and news at work, you’ll find this invaluable.

  • Google Reader: Uses your Google account and is one of the best readers available. HTG Author recommended.

Email Clients With RSS Feed Features

Social Bookmarking and Link Sharing

  • Reddit: Similar to Digg, Reddit is spartan in design, but functional, and full of fun and ridiculous content.

  • Pinboard.in: A spartan and functional pay service that allows users to browse their own tag clouds and create PDF versions of their bookmarked sites.

Content-based and Grouped Blog Directories

Directories are category based lists of popular blogs, broken down by broad types, categories or genres. Each of them have their own particular look, and most are usually manually moderated. Because so many of them have moderated submissions, you may find listings unique to each service. Searching directories may be a little old-fashioned, but can be a great way to discover quality sites relevant to your interests.

Social Networking and Link Sharing

While readers that don’t know about Twitter and Facebook are few and far between, Social Networks are great ways to keep up with the most important or interesting stories from your favorite content providers. Find and follow your favorite writers—many of them share content through Twitter or Facebook, with some content exclusive to that author’s particular feed.

  • Twitter: Search for your favorite authors, blogs, webpages, or artists. “Following” them on Twitter is similar to using RSS feeds, giving you a stream of content they want to share with you.

  • Facebook: Serach for your favorite authors, blogs, webpages, or artists. Again, your Facebook feed will operate similar to an RSS feed, allowing you to subscribe to pages by clicking the “Like” button.
