Almost three years to the day after it launched its attempt at a social network, Google has removed the last remaining restrictions it had on what name users could go by on Google+ — meaning the search giant has abandoned its so-called “real name” policy, and members are now free to use a pseudonym. But the change seems unlikely to cause any kind of dramatic growth, since those to whom pseudonyms made a difference have presumably already established themselves elsewhere. If anything, it makes Google seem a little desperate.
