Yeah, savvy companies are getting away from the annoying "RT every nice thing people say about my company" with 'fave it and then point the faves at people if they want testimonials". Hostgator does this well: http://twitter.com/hostgator/favorites
I don't understand what you mean by "point the faves at people if they want testimonials". Looks to me like they're just favoriting positive feedback that is sent to them
