Thing 2 is a lot of heavy reading designed to explain why Web 2.0 and Library 2.0 are/will be great opportunities for libraries to maintain their stature and place in society. I agree that Libraries must understand and use every new technology to further their mission and importance in society.I do have an issue with the blog 11 reasons why Library 2.0 exists and matters. It states that "If we are going to play host to non-authoritative content (which it is when it comes from our patrons), then how do we designate that? L2 ushers in an era where this becomes something libraries need to do. There is a lot of fantastic non-authoritative data–we just need to get off our high horses and decide to make it available. The matter of how to mark it as non-authoritative is still pending, of course." There may be "fantastic non-authoritative data" but as I see it there is much more that is less than accurate and much less authoritative. Libraries have to vigilant about playing host to non-authoritative data because simply labeling it as such will not dissuade may people from treating it as FACT.
