You can now snag ratings pretty easily. I got this from Lev Walkin who works at js-kit. Here’s an example:
http://js-kit.com/rating-data.js?
ref=http%3A%2F%2Fwww.cyphgen.com&p[0]=/&jx[0]=0
The first param in the query string is your site URL put through a url-encoder. The 2nd param p[0] is the path to the thing you are rating. In this case just the home page.
I hope this helps and thanks again, Lev and the folks at js-kit.com
