Google+ Is it the answer to Facebook?

[Betty]

For the most savvy Google+ users, however, there was another way to let their friends join: rather than send an invite the official way, all a Google+ user had to do was share a post — message, link, photo, anything — with a non-Google+ user by entering in their email address. When the recipient got the email notification that a post had been shared with them, a link at the bottom took them to a signup page for Google+. And voila, they were in.

I read something yesterday that the loophole was closed - then reopened. Reports today say it's working for some people and not others. The report yesterday indicated he had 350 I could potentially invite.
