So this Friendster-like startup believes they have what it takes to bring about a profit from Blogging content? At first it may sound a bit silly. But on a second pass you will see this is more about the aggregation side of content and not so much the readership side of it.

So many blogs, so little time–and now, so many entrepreneurs hoping to help you sort through them.

As the number of blogs, news services and other syndicated sources of online information balloons, a new crop of start-ups has emerged promising to improve the signal-to-noise ratio. And venture capitalists and veteran Internet investors Marc Andreessen and Ron Conway are right behind one of them.

Rojo Networks, a San Francisco start-up in the blog aggregation business, “is wrapping a communications capability around content consumption,” said Andreessen, Web browser pioneer, Rojo investor and Opsware chairman. “And the killer app for the Internet is and always has been communication.”

The boomlet in blog aggregation start-ups comes as online content increasingly is pushed to readers using protocols such as RSS (Really Simple Syndication) and Atom, which transmit fresh lists of headlines and content summaries to a browser, a Web site like Rojo or a separately downloaded application.
