Easy feed grazing and sharing
RSS feeds are great, but the subscription model used by aggregators is slow and clumsy. After a while, it gets to be too much trouble to subscribe to more feeds. That's why grazing feeds is becoming so popular. Grazr lets you view as many feeds as you want without the hassle of subscribing. Grazr users can freely jump from feed to feed. It's like surfing on a river of feeds.
It's easy to share the joys of feed grazing with visitors to your site. You can add embedded copies of Grazr to your pages, as you see here, or we have a cool badge you can use that opens Grazr in its own window. You can even start Grazr as part of a hyperlink attached to any image or text.
This is a powerful little tool that can be easily added to your site I'm, using it here
