Sync contact information by name of contact and name in Social Network
Would search Facebook or Twitter or Linked In for a similar name. Would for confirmation if the contacts were the same.
This seems to be essentially identical to http://rainmaker.uservoice.com/forums/57582-general/suggestions/1114889-pull-social-network-friends-into-google-contacts – concentrating votes and discussion there would prevent unnecessary dispersion. @Rainmaker, would you consider merging these two suggestions?
