The real-name G+ kept me away as I knew it was doomed. Many of my female friends use an alias, or a mis-spelled name, to avoid stalkers or getting hassled. Few of my guy friends would want to be on a service with no women on. Even I have 2 FB accounts, one for work friends and another for family. The fatal flaw, the one that killed various biometric companies as well as G+, is that in real life we are different people at different times. The person you are at work is not necessarily the person that is on a picnic with his family taking snaps of his loved ones or of wildlife.
