Web 2.0, Libray 2.0

I read all five articles. The first and last articles were the most interesting. I especially enjoyed Wendy Schultz's prediction of the future for libraries. Who really knows what library 3.0 or 4.0 will look like, but it was interesting to read her ideas. The first article hinted at the idea of a giant digital collection with everything in it--books, journals, blogs, podcasts. My guess is that one day we will have a national library like this. If so, then what will local libraries look like??? Will they only be used by folks who don't know how to use or don't like technology? Or will web 2.0/library 2.0 and even bigger technological innovations lead to libraries evolving into something that we can't even come close to imagining?
