I'm respecting Fred Wilson more and more with each article I read from him. But I think this article really has some deep thoughts that are expressed in clear ways.<p>1. Not "web apps" but "Internet services". It's a bigger world than just websites or backend services. iOS, Android, Desktop native, Web App, cloud, etc. Developers need to think broader in not just what website or app do I want to make but what kind of Internet service do I want to provide.<p>2. The irresistible economics of large networks. In other words, large networks make sense economically. They will find a way to be profitable. And they will transform the world, relationships, business, culture, worldview. Large networks might just be the most transformative force in today's world.<p>3. User experience rules. It's not about how techy or complex your project is, but rather what's the experience of the user. How does it add value to them? And do they LOVE it? This is what differentiates various Internet services and allows them to gain traction until they can fully utilize network effects to make their site better than anything else out there.<p>4. Launching new large networks is more challenging. People are already on FB, Twitter, Tumblr, etc... and to create new large networks can be difficult because people already have their loyalities, and the current large networks are just getting better and better. Those that can start large new networks are doing it in a way that's a different approach than what's out there.
