Will +1 make it into dictionary?

Funny how Google+ hasn't exactly set the world on fire but one aspect of it has going viral -- the use of +1. 

I'm hearing and seeing "+1" more and more. If you're not in the know, +1 is a synonym for:
Amazing
Awesome
Fabulous
Great
Wonderful
Astounding


In other words, when you say +1 or write +1 it's like applauding. Kind of like clicking the Facebook "like" button. +1 is the new high-five!
