Web 3.0 refers to the next stage of development of the World Wide Web, characterized by greater integration between online and real world experiences. Groupon is seen as an example of Web 3.0 because it enhances aspects of social networking by allowing users to find local deals and discounts, while also building connections to local businesses. However, Web 3.0 and companies like Groupon still face challenges around overdependence on the internet, limiting the types of deals offered, and ensuring businesses continue to provide discounts. The future of Web 3.0 is uncertain as technology may change the dynamics significantly.
