A lot is being made of the fact that in librarianship, Average is No Longer Enough. Was average enough at some point previously? Possibly; it doesn't matter. What matters is that there are enough librarians in the profession who love it enough that they don't want to be average, rather than reluctantly excelling themselves because they've been told to do so at a conference or by a blog post.
I predict that the total number of information professionals (in the current understanding of the word) will shrink at a fairly steady rate during my career. The Average will probably be the first to go (the Really Bad being, in my experience, remarkably stubborn). It'll be a Darwinian process - the people that really love this will probably be strong enough to survive, because they're the ones likely to be enthusiastic about embracing new challenges.
In a job market where there are far more qualified professionals than there are professional posts, the whole idea of trying to turn the drifters into yet more super-librarians is perverse anyway. The people who think average is enough are probably never at the kind of events where people say it isn't. Let's stop telling each other what we already know, take the non-existence of THE SPOON as read, and use our time in conferences and on social media to talk about something more useful - like specifically HOW to find your 'extra' rather than just the fact that you need to.
