I Joined Google Plus Today! BUT WHAT IS GOOGLE PLUS?

It is a social networking service in beta phase,
in which users can join by invitation only -



Social circles allow selective interaction; the number is unlimited
Web conferencing option for up to 10 participants
Instant upload of photos, pictures on Google+
‘Huddle’ turns different chats into a group chat
Google Plus would soon release mobile applications for Android and iPhones
