What is Web 3.0?

A.k.a. the Semantic Web
A term coined by Tim Berners-Lee, inventor of the World Wide Web. In the Semantic Web, machines can read Web pages (from metadata) just like humans read websites (from text and images).

Why metadata matters
Web 3.0 will make connections with information: Metadata (machinereadable data that describes other data) will create a massive database that can produce more accurate search or recommendation results.

Like a personal assistant
Web 3.0 will be able to learn more about you as you search. Finding answers to complex searches becomes easier as a browser can look for the context (e.g., your location, time of search, past searches), and more than just the keywords of your query.

Wow, Google Now

Google Now is an intelligent personal assistant app that can pre-empt your needs from what it learns about you and your routine. For instance, it can tell you the best time to leave your house based on the real-time traffic conditions of your usual morning route.
