I just released a new plugin "Best Post Page", that automatically generates a page called "Best Of Post" that dynamically determines the best post from your blog. It uses the WP-ShortStat plugin to get statistics about the posts (view, comments, etc) so you need that installed. The "Best Of Post" page makes and call to an optimization engine to determine which posts are the favorite of your readers.
Here is the WordPress Plugin Directory page:

Here is the plugin homepage:

This is my first plugin so let me know what you think especially other stats plugins that this should support.
