Redinfed the way the web was used. Changed from being a "read only" web to a user genterated web. It's crazy to think how fast everything changes. The world barely gets anytime to settle before something else changes. Even the creators of the tech can't keep up with their own creation. With Web 2.0 people were able to make their own things just allowing the platform to grow rapidly. When you give people the opportunity to take a medium and play with it you never really know what all the outcomes could be.
