Hi!
We added the table to vastly improve recommendations which the majority of our users asked for. You can download the old versions of the plugin here: http://wordpress.org/extend/plugins/wordpress-23-related-posts-plugin/developers/
(anything before 2.0 is with the bad recommendations).
@Naziman, if you have enough pageviews and the right kind of content you can potentially earn money with the plugin.
Best,
Rok
