Scott Plutchak discusses blogs in his editorial in the latest Journal of the Medical Library Association:
Plutchak, T Scott
I see blog people
J Med Libr Assoc 93(3) July 2005: 305-307
It's well worth reading (not because he kindly mentions this blog) as an excellent survey of current thought on blogs, blogging and their library applications, as a gentle and reasoned riposte to Michael Gorman, but above all because he thinks carefully and deeply about the relationship between thought, language and writing. He concludes by suggesting that, with blogs, librarians are about to enter the third stage of a technological innovation, where the technology at last offers opportunities to do something absolutely new. I think this is true, not just of blogging, but of the plethora of social software tools we're starting to use: Flickr, CiteULike, del.icio.us and so on.
