A colleague forwarded me a fantastic article from Ad Age "It's Web 3.0, and Someone Else's Content is King". The article is worth a read for anyone in the content business. The author, Matthew Creamer, suggests that Web 3.0 will be about monetizing the web's openness and points to examples in the news business of websites aggregating other people's content for profit. Are content aggregators in fact growing in popularity? The author cites Michael Wolff of Newser: "The space is heating up". According to internet usage data, is it?
