I prefer a domain and my own server. But nobody will see what I write. The average user can't use G Reader. They can use twitter and facebook. Why hasn't this issue been solved? I want a network with friends who are users that gives me control. Contradiction in terms?
Either use a distribution list, or have someone in your group set up a forwarding address that forwards to all the people in your group.
No, there's no place to go to, but it's much more conversation oriented than openly stalking your friends on their social network pages.
I don't want to look at my friends or their stuff, I want to talk with them.
