<< Millions of people around the world use Google Groups to power discussions with the groups and communities they care about. We have been working hard to improve this experience, and today we are happy to announce a sneak preview of the brand new Google Groups.

The new Google Groups lets you quickly find and browse the content you care about. Your favorite groups are always available in the navigation bar on the left. Using keyboard shortcuts, you can speed through discussions to get to the ones that interest you most. (Tip: Hit “?” to see a list of shortcuts.) >>
