It shouldn't be all paid Original post link: http://iron.randombase.com/2008/05/31/wordpress-widget-time-spent-on-blog/
I still do not understand if you are just posting about this addon, or asking a question about it, or commenting on it being free or what, but whatever it is it wasn't clear. In addition to that, I do not appreciate the nasty pm you sent me about me asking what the topic was about...
If you only read the topic thread you would know that he was talking about his widget plugin for wordpress. The widget plugin shows how much time all users who visited your site have spend on your site... Ontopic: Looks impressive!
