Hi from Bavaria/Germany!
I totally focus on Web 2.0 apps as to education. Feel free to check some of my sites. And I checked your wiki - interesting.
I´ve got a project wiki as well: http://e-digiskills.wikispaces.com
And I created the biggest group about digital teaching methods on Classroom 2.0: DigiSkills with now 301 members. Would you like to join as well?
