Google introduces Messaging in Google+!

It has been quite some time that Google Plus was launched and one thing which most people who used the social network by Google have been whining about - messaging is now implemented. While there has always been the method of doing that, the dedicated button for doing it has been missing. 

From now onwards, when you visit a person's profile page in Google+, you will see a little icon which would open a box and you can send him a message. For those who want to know why and where the messaging option has been, well, all you have to do is to create a new post, remove all the other circles and public option from the sharing options and include the person you wanted to message and post the status! 

But we do bother to ask: do we really need a messaging system with Google+? Google already has/had GMail!
