I am excited to have joined Google Wave now its gone public. I have been waiting for quite some time to join and had asked everyone I could think of to send me an invitation but they had all used them up already! Now I am in! I have found several really useful tweets through @ictclassroom re @willnolan on twitter. There is a really good slideshow by John Jennings with ideas for using Google Wave in Education. Let me know if you'd like me to send you an invitation, there are lots of possibilities to communicate and collaborate.
