Google is beta testing Groups 2, a free email list service destined to replace its Usenet archive (Groups 1, which it builds upon). It won't suffer exactly the same fate as Usenet as it allows public, moderated and private lists. Groups 2 shares login with Gmail and of course has a nice and usable design. I created a group called Groups if you want to play and have a conversation about it: http://groups-beta.google.com/group/groups/ Server errors happen occasionally and I encountered errors using a private list and even spelling errors: Visit http://groups.google.com/group/groups/about to join or learn more about who is alloed to post to the group. Love it. The cost of group forming just fell again. And Yahoo has a real concern (the war) and there is more to come. An email overlay on Usenet essentially brings Google on par with Yahoo Groups in one swell foop. But still, the good groups aren't lists anymore, but spaces and feeds. UPDATE: Groups to have ATOM feeds
