The first wave of digital evangelism has passed. With the dot-com bubble burst and with the help of John Seely Brown and Paul Duguid, among others, we are much less attracted to the pitch that all problems will be solved by the application of massive amounts of data.
Around the same time, Google proved that there is an extremely usable middle ground between cataloged, curated information sets and hopelessly disjoint stacks of data. Users increasingly choose the convenience of Google, and more recently Wikipedia, Flickr, and YouTube, over the authoritative thoroughness of library-mediated research.
Librarians cringe at amateur cataloging. It’s like home dentistry. Google’s black-box PageRank reflects the “uniquely democratic nature of the web” by choosing relevant information based on proxies for trust, reputation, and authoritativeness (not expert assessments of those qualities). Flickr and YouTube use “Web 2.0” social tagging techniques to roughly categorize content. Even non-librarians can appreciate the pitfalls of letting just anyone add meta-data – they’ll get it wrong.
But talking to librarians, I’ve started to appreciate whole other levels of control over the process and content of cataloging. IANAL — I am not a Librarian. The following discussion is for entertainment purposes only.
