You must have heard about “Web 2.0” and “Web 3.0” ​in the blockchain world, .
But what exactly is the difference between Web 2.0 and Web 3.0?
For us to make any sense of what we mean by “Web 3.0”, we need to rewind to Web 1.0 and start there.

Web 2.0 is simply the web that we know today.

Instead of static content, the web became a place for dynamic content, one where users are now able to interact with content published on the web. This user interaction became possible because of the invention of technologies like JavaScript, HTML and CSS, which allowed developers to build apps where users can interact with content in real-time.
Web 3.0 is a Semantic Web. This means that rather than just searching for content based on keywords or numbers, we can use AI to understand the semantics (i.e. meaning) of the content on the web. This would allow machines to understand and interpret information like humans (instead of like machines). The main purpose of the Semantic Web is to enable users to find, share and combine information more easily.
However, these days, the term “Web 3.0” has evolved to mean a lot more than just the Semantic web. More specifically, blockchain enthusiasts who are building Dapps use the term “Web 3.0” to describe the idea of building applications on an open and decentralized architecture.

According to Ethereum here are some reasons while web 3.0 differs and seem better than web 2.0;
*Anyone who is on the network has permission to use the service – or in other words, permission isn't required.

*No one can block you or deny you access to the service.
Payments are built in via the native token, ether (ETH).

*Ethereum is turing-complete, meaning you can pretty much program anything.

*Combining such capability with natural language processing, Web 3.0, computers will distinguish the information just like humans to provide faster and relevant results.

*Three-dimensional design can be used widely in the websites and services at Web 3.0. The museum guides, e-commerce, computer games, geospatial contexts are some of the examples that make use of 3D graphics.

I'll like to appreciate Blockgames in conjunction with Nestcoin's site and Zuriteam's site for the opportunity to dive deeper and understand better the concept of web 3 and Blockchain.
