Losing Library Jobs?!

Today I found the article linked below about the reinvention of libraries, and specifically how competitors occupy niches in the 'reading ecosystem'.  The article's main thrust is the competition that start-ups bring to libraries, and how traditional systems should be learning from and networking with these new organizations in an effort to remain relevant.

I think the article is interesting for a couple of reasons; one, it's neat to find additional tools and resources to investigate, and two, we look at these resources and see so much more than a library.  At least, we purport to, right?  None of us ever show off our pages, boards, stories, or postings and say 'look how great this is, it's just like a library!'... interesting.  All of a sudden I find myself wondering what I am missing at the brick and mortar library.
