[Web4lib] Lists versus Tags design idiom

[Walker, David]

Hey All,
 
I have a metasearch application [1] with a 'save record' feature.  Right now, I'm working on giving our users a mechanism to organize those saved records.
 
I'm leaning towards using a tagging idiom in the interface [2], but have some lingering doubts. I've noticed, for example, that tagging is most often implemented for sites in which the user *generates* the content (e.g., blogs, flickr).  While sites that allow you to search and save records usually employ a list metaphor (e.g., amazon [3], istockphoto).
 
Anyone have a good example of a (non-library) site that allows you to search and save things, and then *tag* them?

[3] Amazon apparently has a tagging mechanism, too, but it's rather (to me) obscurely implemented.
