You are wrong to suggest that you have to convice your friend to get on this. Your friends don't even need to be on chatterous to stay connected to you.
Chatterous is just social glue - they don't even bind you to the site.

I missed that bit. How?

Ah so users to contact a group "foo" would google mail, email "foo@chatterous.com", or "text CHTR foo <msg> to 41411" then?
How do they get the message? Do they still have to sign up to see it?
Nope. They will get an e-mail or SMS or gtalk message, and they would reply simply by replying to that e-mail/SMS/gtalk bot. Your friends don't have to sign up. But as the group creator, you need to add your friends' contact information to add them to the group.

Ok, that solves the signup problem.
So you still need to get the contact details. Not as hard as getting friends to sign up. What is the advantage of non group creators (non-admins) signing up then?
You get the ability to direct your messages to what you prefer. Say a friend added your e-mail to the group. By signing up, you can route the messages to your gtalk or sms or web instead.
