Edublog and learnerblog.org
Some talk going on about edublog.org being blocked by servers. It isnt being blocked here in China yet. What a great tool for educators and students. Built on the open-source WordPress blogging program the site is a great place for educators and students a like to get their blogs up and running. I use WordPress to run 3 blogging sites and find it does everything I need it to do. Educators will find it easy enough to get started and students will have fun not only blogging, but learning a little php scripting as they add on extensions to customize their blogs. Make sure that your students and teachers have access to this site.
