Yes I see what you mean but… all of them are ‘only’ for rating posts or other entries inside your blog…
What I need is a plugin such as the above mentioned Rate Anything:
Rate Anything lets you add lists of ratings for any items you choose, set up through an easy to use admin interface. Rate your friends, movies you’ve seen, anything you choose. Items are rated on a scale of 0-5 stars.
Anyone knows where the Rate Anything website has move to?
