Congratulations to Dave, Brandon, Gaku and the rest of the team for launching the beta version of Google Groups 2. I’ve only played with it for a little bit but it looks good so far. Now here’s one of the really interesting things. The new groups is an intersection of USENET and mailing lists, and every group has two Atom feeds, one for topic summaries and the other for message summaries. This means that you can now subscribe to USENET groups with your favorite Atom-aware aggregator. The format of the URLs for the feeds is: http://groups-beta.google.com/group/USENETGROUP/feed/topics.xml http://groups-beta.google.com/group/USENETGROUP/feed/msgs.xml where USENETGROUP is something like ‘comp.arch’. It’s not quite perfect yet, but it’s a great start!
