Google+ should do what a lot of social networks have done in the
   past: you can get extra features if you upload a picture of
   yourself with your user number somewhere on it. They could have
   multiple levels: Limited user (pseudonym user), regular user
   (like it is now - real name, any picture), and super-user (real
   name + verified self-pic). You can have the choice whether or
   not to publically *show* your selfpic with your user number -
   but it would be something they could do. (this will probably get
   a lot of ppl mad at the idea, who are fighting for
   semi-anonymity (which i don't have a problem with at all) - but
   it is something google could do as an alternative to wanting
   people to pay - or perhaps if you want an Ad-free google+ you
   can verify your identity. ('cause we know the ads will be
   comin')
