They've stopped the invites. In fact, they essentially revoked invitations ... i.e. people I invited last night couldn't use their invitation email this morning. Unless Google turns it on soon, they're gonna lose a lot of good will. They've already managed to tick me off.<p>I also find it funny that people were using Facebook's wall to distribute Google+ invites to their friends. And I always thought that seeding a social network was hard :-p
After having played with Google+ for a few hours, I find that the Circles feature is deceptively complicated, and can lead to unintended information leakage.<p>I've described it further here: <a href="http://news.ycombinator.com/item?id=2714333" rel="nofollow">http://news.ycombinator.com/item?id=2714333</a>
I have to say, classifying my contacts is stressful. I created an "Inner Circle" and I'm thinking about creating a Professional one as well.<p>Or more likely I'll just stop playing with it.
