So what is RSS?
Really Simple Syndication (RSS) lets you subscribe to receive updates using a valid RSS reader. Rather than having to regularly check the web site you are interesting in, RSS feeds update automatically. This means you simply have to check the feeds to get the latest content. You can also use RSS to update you via email.
Most modern web browsers (IE 7 and Firefox) support RSS feeds. This means you can subscribe to the feeds and check them directly from your browser. Firefox even allows you to drag RSS feeds onto the tool bar and use them in a similar way to bookmarks.
A web site that I currently use is Netvibes; that allows me to aggregate all of my feeds and organise them into relevant areas. Netvibes also supports widgets making it easy to check a wide range of regularly used websites from one page. I use Netvibes to aggregate all of my favourite mobile blogs into one handy page creating my own mobile dashboard. Netvibes also keeps track of which posts you have read; working in a similar way to email. I use some of the Netvibes widgets to check social networking sites such as Facebook, my personal email provided by Google and my friends Flickr sites all from one page.
