Web 2.0 was all about making the internet more interactive and giving users the ability to participate instead of just consuming content. This meant introducing features like commenting, liking, sharing, and uploading, which made platforms like YouTube, Facebook, and Wikipedia possible. Technologies like AJAX and APIs were key because they allowed real-time updates, like refreshing a feed without reloading the page. The focus was on creating a space where people could interact, share ideas, and collaborate.

Today, things are way more advanced. Interactions are now smarter and more immersive, thanks to AI, real-time collaboration tools, and even VR/AR. For example, AI predicts what you want to see or do, voice assistants let you interact without typing, and augmented reality blends the digital world with the real one. Instead of just participating, we’re now co-creating and interacting with systems that adapt to us in real-time. The jump from Web 2.0 to today is like going from writing letters to having live conversations—it’s all faster, smarter, and way more personalized.
