These are terms that libraries and librarians should be familiar with, but unfortunately, I think we as a whole are not. The term librarian usually brings to mind a reclusive old lady who just wants to be left alone with her books. Well, things have drastically changed. There is so much more to libraries than books, and librarians are now joining to local roller derby league!
This post and this video are excellent reasons why librarians need to have a better understanding of Library/Web 2.0 technologies. Libraries are supposed to meet (and hopefully exceed) the needs of their community; we are teachers to the public of these new and innovative ideas. It is our responsibility to serve the public, and librarians need to be open to the ways in which technology is changing. Web 2.0 is about connecting people. What better place is there for this to happen than a public library.
