This may become a series:
Having taken Andy Burkhardt's suggestion and set up a few feeds from Twitter searches, I've seen local tweets about books, reading, study etc ....
And so I wonder (because I am not yet a reference or social librarian): if a social librarian were to pick up messages like these, what would be a suitable reply? Ah. That, I guess, will derive from the strategy which would have preceded (and been reviewed perhaps after) the listening stage :-P
To...
... might s/he (the librarian that is) tweet jovially about finding it at the library with the permalink to the item in the catalogue? (assuming there was one,).
This sounds like a fun game.
