@Ted Clayton - The problem is finding one and seeing that it is popular. The popularity does not show on a time basis and while the plugin may work today, it may break when the next wordpress release is made. There should be something within wordpress that informs the user that the plugin(s) they are using are out of date and do not work with their version of wordpress.

While the rest of us will look at plugins in depth, testing them on a test install, most users do not do this, especially new users which wordpress seems to be aiming for. New users have a bad habit of assuming all plugins work with wordpress, so they add all the plugins they want and then wonder why their database is so large and their site doesn't work properly.

I wish I could show you some examples of customers where they have so many outdated plugins, it is insane.

If wordpress is targeting new users, they need to make it more user friendly and inform the users of incompatibility issues with plugins. They have already started to do this by warning users when they add the plugin, but after the plugin has been added, there are no further warnings that the plugin is out of date unless an update is available.
