Myspace was killed by backwards compatibility. One key aspect of Myspace is how customizable it is. As any programmer can tell you, this limits the ways features can be rolled out. For example, you want to have a new layout? Too bad. It will break the users customization. You want to add a new button? Too bad. There is not a coherent place where you can add it. You want ajax? How will that break users layouts?
