The story isn’t a lot different. The open Web needs us to program to the Web standards. If we program to tools, we pit standards against the innovations that tool has brought to the table.
WebKit has led many new developments and that has made it popular with a lot of browsers, especially for mobiles. If we, the developers, focus only on WebKit and ignore others, we will end up with killing either the standards or the WebKit. Let us learn from history – use the new technologies, but make sure we support the standards, and on the way help standardize those innovations.
