Feedweaver allows you to create your own personalized RSS feeds. You can create your own feeds by combining source feeds from your favorite websites, and use filters to choose what you want in it!
Combine mutiple feeds
You can combine multiple RSS feeds into one. For instance, you can combine the RSS feed from cnn.com, times.com and bbc.co.uk into one RSS feed, which later on can be customized by yourself.
Customize your feed
Customize your combined feeds by using keyword filters. For example, you can extract all the news about "iPod" from your feeds with just one click.
Share your feeds
You can easily share your feeds with friends by giving them the feed's URL, and they don't need to login to view the actual feed, as all the feeds are available to everyone who knows the address.
