What is RSS and why would I want it?
RSS is a way of getting “feeds” of content, like shows brought to you from web sites of your choice. You can read RSS feeds by getting a special browser called an “aggregator.” Once you have an aggregator, you can find feeds on the web and subscribe to them. (Tip: look on your favorite sites for RSS symbols like this one 
.)
If you read various websites regularly, RSS is a great way to save time, because instead of you going to check for new content all the time, it does that for you, and then brings all the new content into one place for you to view it. Another nice thing about RSS is that unlike signing up for an email newsletter, with RSS you have control over whether or not you receive the content. You’re not giving out your personal information, and you can delete a feed at any time.
