New 23things

I'm officially addicted! I've been googling "23things" to find other groups doing similar exercises. Some of them are for public librarians and others are for school librarians, so they are even more relevant for me. Here are a few of my next explorations:
http://bookvideo.ning.com/ is a ning to promote books and reading.
http://teacherlibrarian.ning.com/ is a ning for school media specialists.
http://23thingsonastick.blogspot.com/ is sponsored by the Minnesota Library System.
http://bighugelabs.com/flickr/deck.php, in which one can create a trading card to then post on a blog
http://k12learning20.wikispaces.com/23Things is a wiki that incorporates 23things exercises.
http://tametheweb.com/sljlearning20/ is School Library Journal's version.
http://schoollibrarylearning2.blogspot.com/ is the California School Library Association version.
http://librarystream.wordpress.com/about-the-learn-more-series/ is the "Learn More" series by Steve Campion.
http://sociallibraries.com/libr246-12/assignments is a grad level library sci course called Web 2.0 and Social Networking Tools offered at San Jose State by Meredith Farkas. There are very thoughtful questions to consider while investigating the tools.
