Subscribing to a site’s RSS feed means you do not have to waste time visiting several websites to read your favorite content. Instead, you use feed reading software or a website to get the latest articles, news and information. An RSS feed reader allows you to collect the feeds of your favorite websites (provided they’re available in an RSS syndicated format) all in one convenient location.
If you don’t use it, I recommend that you start. RSS is a HUGE time-saver.
