When I was in college, I started a startup that was helping you to store your online notes, and we did try to connect people based on similar interest topics via your stored notes. And we called this semantic web, and my partner at the time he said this is Web 3.0. As you guys figure out we were so wrong and my co-founder that time he was so sure this is the new internet. Connect everyone based on interest without any search.
If you want to what’s Web 3.0 and what we will be use cases and current trends. You should stop what you are doing and listen this podcast with Tim Ferris and his guest Chris Dixon and Naval.
