Zoomclouds offers a unique presentation of the content on a website that has RSS: in tags. It looks something like this:
Alas, Zoom Clouds only supports one feed per cloud. Wouldn't it be great to have a Zoom Cloud on your website offering a mix of several feeds? Yes, it would! And yes, it can be done.
If fact, it's rather easy. First, gather the feeds you want to use. Then, visit FeedBlendr, a website that offers just what its name pretends: blending feeds into one. Add your feeds and let FeedBlendr combine them into one new feed. You'll get a unique URL that you can copy and paste as a source for your Zoom Cloud.
Obviously the example comes from a bunch of jazz websites.
