Here are a few ideas., since you asked (I think?) Stefano Mazzocchi: http://www.betaversion.org/~stefano/ Creator or Cocoon, one of the people behind the Simile project, now at MetaWeb ... I think Stefano's experience with public speaking, open source software, data processing and the web would make him a compelling keynote. Andy Powell: http://www.eduserv.org.uk/foundation/people/andypowell/ Long time metadata wrangler, and moving force behind organizations like UKOLN, JISC, Open Archive Initiative, Eduserv. Andy's been a strong advocate for the use of web technologies, and web architecture in the digital library space. Ian Davis: http://iandavis.com/blog/about CTO of Talis, architect of their RESTful semweb platform, co-author of RSS 1.0, creator of FRBR RDF vocabulary, articulate and experienced speaker on the use of the web and semantic web technologies, particularly (but limited to) the library space. Tim Spalding: http://www.librarything.com/profile.php?view=timspalding The guy behind LibraryThing. His insights into the communities around books and libraries, and how to enable them on the web are fun, invigorating and inspiring. Carl Malamud: http://en.wikipedia.org/wiki/Carl_Malamud Long time advocate for Internet technologies for the public good. Most recently involved with making public domain data sets available to the public w/ public.resource.org. Jon Orwant: http://www.orwant.com/bio/ Perl hacker, author, former CTO of O'Reilly, now at Google Book Search. Would be fun to hear where he thinks libraries and books, and hopefully he'd throw a mug or two. //Ed
