Gavin King is often thought of as the developer of Hibernate, but he deserves as much credit for making Seam, the web framework that unifies JSF and EJB3. Now he's going for the standards hat, making Seam into "Web Beans", a Java Community Process standard (JSR-299) that should get incorporated into future releases of Java EE. Check out this Web Beans Manifesto, which I agree with and which pretty much sums up why Seam/Web Beans, as it is now almost trite to say, "matters".
