I was just thinking about this a little while ago. Since a great deal of us are signed up for the HubPages Ad program and our PayPal info is already in the system, wouldn't it be nice if HubPages could somehow add a PayPal button to hubs so that hubbers who are logged in can pay other hubbers directly for posts that they find really useful, creative, enjoyable, etc? A set your own amount sort of thing? Any reasons why it would be inadvisable? I don't know. Just a thought.
