Made a first post and google seems to have (very helpfully) sent emails to people who don't have a google+ account yet. It asked me if that was ok, very nice :)
So! If anyone reading this would like an invite, PM me your email and i'll get one to you. You might have to wait some indeterminate amount of time before it lets you in, but it'll happen. I previously signed up for the waiting list and nothing ever came. So getting a friend invite seems the best option right now.
