I finally got around to posting (on the WJUG site) the link for Thilo's
slides from his December talk. (!) They can be found at
http://www.frotscher.com/presentations.html.
BTW, for those interested in web framework comparisons, there are
several interesting presentations in a similar vein to Thilo's at
http://raibledesigns.com/rd/page/publications.
