The Gardner paper seems to be turning the argument towards libraries by saying they have to make their ILL systems more streamlined in order to compete with a Twitter hashtag.  While it is true that interacting with and ILL system isn't the easiest thing in the world, users don't have to do that to get an ILL - they can just send an email with the same information as in the tweet to a library and the librarian/assistant will do the rest.  Or tweet to the library if they have an account.

Gardner, et al, do also argue about the benefits of education in information retrieval; not just that users will be able to find articles, but they will develop skills in "persistence and flexibility in searching".  If the users resort to #Icanhazpdf and then don't get the article, do they think it can't be done or do they then contact the library?  We need to get across they should do that first.
