Rojo unveiled its next-generation Web-based feed aggregator to an invitation only list. Chris Alden is excited. Rojo has already indexed over 700,000 feeds, some able to be sorted by topic and popularity. A recommendation engine is built-in. Friends and colleagues can connect to each other within Rojo and flag stories for each other and share what feeds they are reading. Rojo Networks also has some P2P talent in Brad Neuberg and it will be interesting to see how that technology could be utilized given Rojo’s Web interface.
