One thing I'd actually like that could be classified as "social" is link scrubbing, i.e. given something like a twitter feed give me a list of the links posted therein over a certain time, de-shortened and with the proper page titles. With quick options to a) add them to my bookmarks, maybe with a certain tag ("read-later" or "<author_name>"), b) delete them, c) instapaper the content.
