Google for Educators was a new find for me. I have no idea how long this site has been around. The About page was not working so I am guessing the site is relatively new.
Google For Educators is intended as a portal for K-12 educators. The site suggests educational applications for Google Tools (e.g., use Google Docs for process writing activities, Google maps to indicate where famous historical pictures were taken) and a discussion area in which teachers can reply to Google suggestions and offer other comments.
The site had nearly 2000 “members” when I visited. Google has the draw and resources to create the critical mass likely to make this a successful participatory site.
