Google is adding another new feature, debuting the beta of Google Groups 2. The new version will allow users to create their own mailing lists or groups, either public or private. SearchDay has more. Plus, the new Google Groups are offering Atom Feeds for each group, so you can have new posts downloaded directly into your newsreader! You have to dig a bit to find them — just click on the More button for a particular group, and scroll to the bottom of the next page.
