Where is the Metadata?

Yes, I am still recovering from the aquabrower presentation and the fact that even Amazon uses the metadata provided by OCLC which is the same metadata libraries use. At least that is what I inferred from some recent information, please feel free to correct me if I am wrong. The point is, it's available and why isn't my library using the metadata and technology to it's full potential? Even without AquaBrowser, the options are endless and awesome and user friendly and cool and technologically updated and aesthetically pleasing and descriptive and what is taking so long for public libraries (not all) to start using this great metadata?
My upset was re-ignited earlier today as I was looking up a public library in California for a patron/customer/guest. I accidentally stumbled upon a library in New York, The South Huntington Public Library, and it is awesome. They have 24 hour librarian reference; RosettaStone, which is online software to learn languages; SuffolkWave, free digital downloads of books, movies, how-to's and music; next reads (self explanatory); online homework help with tutor.com; covers of materials along with descriptions; online signup for programs; beyond Google, a very user friendly guide to using databases; and the catalog, what can I say, it's not a one box search like Google or AquaBrowser, but it has a clear and efficient search including loan rules, request for purchase, ipod options and more, all available for the patron/customer/guest. I just need to say that I think it is very COOL and my library does not have any of these things. Ok we do have ebooks, but it seems so small in comparison.
So what is taking many public libraries so long to use available technology and metadata to benefit the patron and make the library more user friendly? I am looking into it and will try to report back if I find a substantial answer.
