New Plugin Proposal – Anyone interested?

We’re making a new plugin that (when added to your blog) allows visitors to save your post(s) in a list of their favorite links. Links are organizzable, have a thumbnail screenshot of the link address, and commentable (write a comment to remind yourself why you were interested in that link). A new take-off on the sharing buttons that are so popular these days. The design is all very web 2.0 and uses j-query effects for smooth scrolling and drag and drop.

We’re looking for feedback – do you think a plugin like this could be useful? Would you use it? Critiques? Thoughts? Does it already exist? Any input is very much appreciated. Thanks for your time!
