“The new web is moving beyond connecting pages to interconnecting data objects, concepts, and things. Ultimately Web 3.0 is really about creating technology that more accurately mirrors how we see and think about the world around us.”
- Attention. “Applications that are smartest at competing for our attention—or at helping us understand what we should be paying attention to—will have a distinct advantage in the web 3.0 world”.
- Agents. “As just one small example, you tell it that you want to be kept abreast of upcoming social media events, and it checks Upcoming.org, Facebook, Evite, Meetup, etc. and shares with you the events it finds, allowing you to sign up for them through its own interface.”
- RSS. “Content syndication will be at the heart of web 3.0. It empowers almost everything I’ve been talking about in this post to some extent. Don’t sell it short. Look for ways to use it and build applications around it.”
- Semantic Web. “What if there was a way, for instance, that my blogging software could understand that what I was writing about—in plain English—was an event I was trying to promote, and could translate that information so that it could automatically be shared with Upcoming, Evite, Eventbrite, Facebook, etc.?”
