In my presentations I like to say that people using social software sites like to do library type work for fun. LibraryThing might be the most glaring example of this, but there’s also AskMe. And there’s organizing and adding metadata on del.icio.ius and flickr.
I’d love to see a report on the accuracy and speed of things identified by the ID Please group and Reference Librarians. Fair comparison? Who would you bet on?
