How do I create some simple ajax rating like there is on this page http://watir.com/documentation/ ? Every visitor should be able to rate, I dont need to set permissions. I

Looks like the Watir documentation rating system is set up through polldaddy.

For this particular case, it appears they include the polldaddy javascript which populates the rating div container with their star rating widget. Looks like there's a corresponding javascript object which you can inspect:

console.log( PDRTJS_101132_page_2.avg_rating ); //=> 4

If you had numerous rating widgets like these on a page, and you were able to make a collection of the javascript objects paired with their divs, presumably you could sort them based on that average rating property.
