That's interesting. I like Google+, but none of my friends use it. Inviting them to events would be one way of getting them started. Would be even better if I could invite people without Google accounts by e-mail, to make it generally usable for everyone.

You can do this now. Just type in an email address in the field where you add people/circles. The user who receives the invite can set his availability-status without having a + account. Anything else (posting, commenting, adding photos etc.) requires an account though.
That's great! I'm trying this now. Hopefully Google isn't too clever here, though... I know that of the people I e-mailed use Google Apps, so perhaps Google detects that it's an Google Apps address and enforces Google+ account creation.
