Remind me me to never launch a social network that excludes users from inviting their friends. If you have a Gmail account, you can read a debate about this topic but without a Google+ account you won’t be able to socialize.

From PCMag:

Google+ will not become the social network it wants to be until Google lets everybody in. Open the doors, Google. Take the heat. It’s going to take some time to reach three quarters of a billion users.
