I just joined Classroom 2.0 which is a network of educators interested and active in integrating web 2.0 methodologies into the classroom.  I just joined this morning and already have had several idea generating discussions with other members.  This is a great way for any teacher to learn more about what is working and what is not in the classroom regarding creative uses of the internet.  It’s also a great way to gain resources and join forums for discussion on where web 2.0 is ready to take us (although may have alluded that we are now in the web 3.0 era!).
