I just had an idea, and thought Id share. Imagine http://plugins.jquery.com Besides listing all the plugins with ratings and everything (the usual)... You could REGISTER your site as using a particular plugin.
So when there is a new version, I would receive an email saying, "Hey, you use this plugin and you might want to upgrade. It has the following enhancements." Right now, I can't keep track of all the plugins I've used and what version they are. What is the status of the enhanced plugin site anyway? Glen
