On the Redmond Developer News site, there's a new article about a new idea stemming from the mashups that have become so popular - "feed bleeds".
I call them "feed bleeds." That's because syndicated feeds can be easily bled into one another to form aggregated streams of content. Not only that, users and developers can increasingly control the content mix.
Zend is already playing a part in the development of these "bleeds" via their contribution (a collaboration with IBM) - the QEDWiki software (based on the Zend Framework).
